Claim:
A method for enabling a user to perceive online presence of co-users in an electronic network system, the method comprising: presenting a graphical user interface to a user of an electronic network system for perceiving presence of co-users on the electronic network system; enabling the user to create multiple user-definable co-user lists within a single window of the graphical user interface, wherein the user-definable co-user lists enable perception of the presence of the co-users on the electronic network system; and enabling the user to add a co-user to a first user-definable co-user list and to add the same co-user to a second user-definable co-user list that is different from the first user-definable co-user list to enable perception of the presence of the co-user in both the first user-definable co-user list and the second user-definable co-user list, wherein the first user-definable co-user list and the second user-definable co-user list are presented in the single window of the graphical user interface.
