Techniques are provided that allow users to collaborate in relationship to data views, application displays, applications or events. A user can type in a text view related to a specific view in an application display, and the information is shared with other users that take part in sharing that view. A user that expresses an interest in an event is notified about the event and has the capability to interact, in relation to the event, with other users (e.g. by text). The particular form of interaction (and sharing) can be selectively specified. This interaction is comparable to a dynamic bulletin board where the subject is event driven, and where a user can specify who are allowed to participate. In the case of an event interest(s), users specify their interest (e.g. in other user application events or system events) and the system automatically alerts them to the occurrence of the event.
