wherein the subgroup message is obscured to not display message contents when the message display is not associated with the subgroup member;

determining that a termination parameter associated with the subgroup is met; and

terminating the subgroup by merging one or more subgroup messages into group messages in the message display wherein merging the one or more subgroup messages comprises:

removing indications the one or more subgroup messages are meant for the subgroup members,

wherein the one or more subgroup messages and group messages are displayed together based on a time of receipt, wherein indications that the one or more subgroup message are meant for the subgroup members are removed when the message display is associated with the subgroup member, and

archiving one or more subgroup messages displayed to the subgroup members.

8. The computer program product of claim 1 , wherein the operation further comprises:

receiving a merge command at the group based messaging interface; and

causing a merger of one or more subgroup messages displayed to the subgroup members into group messages in the message display.

9. The computer program product of claim 1 , wherein the subgroup command further comprises a subgroup topic, wherein the plurality of members of the subgroup are subscribed to the subgroup topic.

10. The computer program product of claim 1 , wherein the operation further comprises:

receiving a group message;

determining that the group message comprises a subgroup topic; and

setting the group message as a subgroup message of a subgroup associated with the subgroup topic.

11. A system for group-based messaging comprising:

one or more computer processors; and

a memory containing a program which when executed by the processors performs an operation comprising:

receiving, at a group-based messaging interface server providing message based communication between a plurality of group members, a subgroup message comprising a subgroup command, where the subgroup command indicates the subgroup message is sent to a subgroup of the plurality of group members;

 determining, from the subgroup command, a plurality of subgroup members in the subgroup;

 outputting the subgroup message for display, to at least one client device associated with a least one member of the plurality of group members,

wherein the subgroup message is displayed in a message display of the at least one client device,

wherein the message display comprises both group messages and subgroup messages,

wherein the subgroup message is displayed with an indication that the subgroup message is meant for the subgroup members when the message display is associated with a subgroup member, and

wherein the subgroup message is obscured to not display message contents when the message display is not associated with the subgroup member;

 determining that a termination parameter associated with the subgroup is met; and

 terminating the subgroup by merging one or more subgroup messages into group messages in the message display wherein merging the one or more subgroup messages comprises:

removing indications the one or more subgroup messages are meant for the subgroup members

wherein the one or more subgroup messages and group messages are displayed together based on a time of receipt, wherein indications that the one or more subgroup message are meant for the subgroup members are removed when the message display is associated with the subgroup member, and

wherein the one or more subgroup messages and group messages are displayed in ascending order based on a time of receipt, wherein the one or more subgroup messages are unobscured when the message display is not associated with the subgroup member.

12. The system of claim 11 , wherein the subgroup message is displayed with an indication the subgroup message is meant for the subgroup members.

13. The system of claim 11 , wherein outputting the subgroup message for display comprises:

outputting a renderable object to the at least one client device, wherein the renderable object renders a subsection within the message display for subgroup messages, and wherein the subgroup message is displayed in the subsection.

14. The system of claim 11 , wherein the subgroup command further comprises a security setting, wherein the security setting indicates the subgroup message is to be viewed by only the plurality of members of the subgroup, and wherein outputting the subgroup message for display comprises displaying the subgroup message to only the one or more of the plurality of subgroup members in the message display.

15. The system of claim 11 , the operation further comprising:

receiving a termination parameter for the subgroup, wherein the termination parameter indicates the subgroup will terminate after the termination parameter is met;

determining that the termination parameter is met; and

terminating the subgroup.

16. A method for group-based messaging comprising:

receiving, at a group-based messaging interface server providing message based communication between a plurality of group members, a subgroup message comprising a subgroup command, where the subgroup command indicates the subgroup message is sent to a subgroup of the plurality of group members;

determining, from the subgroup command, a plurality of subgroup members in the subgroup;

outputting the subgroup message for display, to at least one client device associated with a least one member of the plurality of group members,

wherein the subgroup message is displayed in a message display of the at least one client device,

wherein the message display comprises both group messages and subgroup messages,

wherein the subgroup message is displayed with an indication that the subgroup message is meant for the subgroup members when the message display is associated with a subgroup member, and

wherein the subgroup message is obscured to not display message contents when the message display is not associated with the subgroup member;

determining that a termination parameter associated with the subgroup is met; and

terminating the subgroup by merging one or more subgroup messages into group messages in the message display wherein merging the one or more subgroup messages comprises:

removing indications the one or more subgroup messages are meant for the subgroup members

wherein the one or more subgroup messages and group messages are displayed together based on a time of receipt, wherein indications that the one or more subgroup message are meant for the subgroup members are removed when the message display is associated with the subgroup member, and

wherein the one or more subgroup messages and group messages are displayed in ascending order based on a time of receipt, wherein the one or more subgroup messages are unobscured when the message display is not associated with the subgroup member.
