Transmission of instant messages according to availability

1. An adaptive instant messaging awareness method comprising:

receiving from a first user via an instant messaging user interface an instant message for transmission to a second user of an instant messaging system;

determining that the second user is not currently available to receive an instant message by

querying a presence server that stores presence information for the second user, and

receiving an indicator from the presence server that the second user is not available to receive an instant message; and

providing the first user a separate user interface that warns the first user that the second user is not currently available and allows the first user to specify whether the instant message is sent and at least one of a time and a date in the separate user interface when the instant message shall be sent by the instant messaging system upon the first user determining that the instant message shall be sent.

2. The method of claim 1 , wherein the separate user interface is automatically provided to the first user upon determining that the second user is not currently available to receive the instant message.

3. The method of claim 1 , wherein the separate user interface is activated from the instant messaging user interface by the first user.

4. The method of claim 1 , wherein the first user specifying whether the instant message is sent and at least one of the time and the date comprises the first user specifying that the instant message shall be sent as soon as the second user becomes available, during a predefined time period on a day when the second user becomes available, or after a predefined period of time when the second user becomes available.

5. The method of claim 1 , wherein the first user specifying whether the instant message is sent and at least one of the time and the date comprises the first user specifying that the instant message shall be sent when the second user becomes available and only when the second user has a threshold number of instant messaging user interfaces open.

6. The method of claim 1 , further comprising:

determining that a predetermined amount of time has passed before the instant message has been sent to the second user;

sending a message to the first user that the message has not been sent within the predetermined amount of time; and,

enabling the first user to again specify whether the instant is sent and at least one of a new time and a new date when the instant message shall be sent.

7. A computer program product comprising a non-transitory computer-readable storage medium having stored therein computer usable program code for adaptive instant messaging awareness, the computer usable program code, which when executed by a data processing hardware system, causing the data processing hardware system to perform the operations of

receiving from a first user via an instant messaging user interface an instant message for transmission to a second user of an instant messaging system;

determining that the second user is not currently available to receive an instant message by

querying a presence server that stores presence information for the second user, and

receiving an indicator from the presence server that the second user is not available to receive an instant message; and

providing the first user a separate user interface that warns the first user that the second user is not currently available and allows the first user to specify whether the instant message is sent and at least one of a time and a date in the separate user interface when the instant message shall be sent by the instant messaging system upon the first user determining that the instant message shall be sent.

8. The computer program product of claim 7 , wherein the separate user interface is automatically provided to the first user upon determining that the second user is not currently available to receive the instant message.

9. The computer program product of claim 7 , wherein the separate user interface is activated from the instant messaging user interface by the first user.

10. The computer program product of claim 7 , wherein the first user specifying whether the instant message is sent and at least one of the time and the date comprises the first user specifying that the instant message shall be sent as soon as the second user becomes available, during a predefined time period on a day when the second user becomes available, or after a predefined period of time when the second user becomes available.

11. The computer program product of claim 7 , wherein the first user specifying whether the instant message is sent and at least one of the time and the date comprises the first user specifying that the instant message shall be sent when the second user becomes available and only when the second user has a threshold number of instant messaging user interfaces open.

12. The computer program product of claim 7 , wherein the computer usable program code further causes the data processing hardware system to perform the operations of:

determining that a predetermined amount of time has passed before the instant message has been sent to the second user;

sending a message to the first user that the message has not been sent within the predetermined amount of time; and,

enabling the first user to again specify whether the instant is sent and at least one of a new time and a new date when the instant message shall be sent.

13. An adaptive instant messaging awareness data processing system, comprising:

a processor configured for

receiving from a first user via an instant messaging user interface an instant message for transmission to a second user of an instant messaging system;

determining that the second user is not currently available to receive an instant message by

querying a presence server that stores presence information for the second user, and

receiving an indicator from the presence server that the second user is not available to receive an instant message; and

providing the first user a separate user interface that warns the first user that the second user is not currently available and allows the first user to specify whether the instant message is sent and at least one of a time and a date in the separate user interface when the instant message shall be sent by the instant messaging system upon the first user determining that the instant message shall be sent.

14. The system of claim 13 , wherein the separate user interface is automatically provided to the first user upon determining that the second user is not currently available to receive the instant message.

15. The system of claim 13 , wherein the separate user interface is activated from the instant messaging user interface by the first user.

16. The system of claim 13 , wherein the first user specifying whether the instant message is sent and at least one of the time and the date comprises the first user specifying that the instant message shall be sent as soon as the second user becomes available, during a predefined time period on a day when the second user becomes available, or after a predefined period of time when the second user becomes available.

17. The system of claim 13 , wherein the first user specifying whether the instant message is sent and at least one of the time and the date comprises the first user specifying that the instant message shall be sent when the second user becomes available and only when the second user has a threshold number of instant messaging user interfaces open.

18. The system of claim 13 , wherein the processor is further configured for:

determining that a predetermined amount of time has passed before the instant message has been sent to the second user;

sending a message to the first user that the message has not been sent within the predetermined amount of time; and,

enabling the first user to again specify whether the instant is sent and at least one of a new time and a new date when the instant message shall be sent.
