10. The computer-implemented method of claim 1 wherein presenting the proposal user interface includes presenting a proposal user interface that includes an icon for informing a host monitoring interactions between the first user and the second user that the first user is offended by the online game specified by the second user.

11. The computer-implemented method of claim 1 wherein presenting the proposal user interface includes presenting a proposal user interface that includes an icon for modifying the parameters within the proposal user interface, such that activation of the icon enables the first user to modify the parameters within the proposal user interface.

12. The computer-implemented method of claim 1 wherein receiving the instructions to modify the parameters within the proposal user interface includes receiving an indication that one of the parameters within the multiple fields is changed.

13. The computer-implemented method of claim 1 wherein receiving the instructions to modify the parameters within the proposal user interface includes receiving an indication that a modification icon within the proposal user interface is activated.

14. The computer-implemented method of claim 1 wherein receiving instructions to modify the parameters includes receiving instructions to modify a type of online game being proposed.

15. The computer-implemented method of claim 1 wherein receiving instructions to modify the parameters includes receiving instructions to modify an identity of at least one of proposed participants in the online game.

16. The computer-implemented method of claim 1 wherein receiving instructions to modify the parameters includes receiving instructions to modify a level of difficult of the online game.

17. The computer-implemented method of claim 1 further comprising:

receiving, at the client device of the second user, instructions to modify the parameters within the counterproposal user interface; and

in response to receiving the instructions to modify the parameters within the proposal user interface, presenting, at the client device of the second user, a second counterproposal user interface that includes multiple fields enabling the second user to changed the parameters of the online game; and

receiving, within the multiple fields of the second counterproposal user interface, at least one parameter that is different from the parameters included in the second counterproposal user interface.

18. The computer-implemented method of claim 17 further comprising iteratively responding to further counterproposal user interfaces until acceptance or rejection occurs.

19. A computer system for facilitating interactions between users of a computer network wishing to play an online game, the system comprising:

means for presenting, at a client device of a first user, a proposal user interface generated by a second user, the proposal user interface including multiple fields configured to include parameters of an online game specified by the second user;

means for receiving, at the client device of the first user, instructions to modify the parameters within the proposal user interface;

means for presenting, at the: client device of the first user and in response to receiving the instructions to modify the parameters within the proposal user interface, a counterproposal user interface that includes multiple fields enabling the first user to change the parameters of the online game;

means for receiving, within the multiple fields of the counterproposal user interface, at least one parameter that is different from the parameters included in the proposal user interface;
