The project went on from 1995 to 1998. Web4Groups primarily supports different-time communication, i.e. communication where all users need not be active at the same time. Participants are of course not prohibited from participating at the same time, but the software does not provide facilities for immediate exchange of data between simultaneous participants. The Web4Groups software provided or was planned to provide the following functions.
All members can send contributions, which are immediately made available to all members.
A personal board for personal information and collection of links to important items as chosen by each user. Activities to discuss ordinary world wide web-pages. Any Web4Groups user can start or join the annotation activity on any existing web page anywhere in the world. A thesauri is typically developed and used by members of one or more activities within a special area to define terms in that area. Full e-mail interface with MIME support.
