Soon, the discussion gets too complex and too divers for participants to follow. The subgroup-formation function detects the need for the discussion to be split up into smaller subgroups including separate forums for

oil prices and government action kids' education

and subgroups for various aspects of the topic, e.g. ecological, social, financial and traffic policy aspects. There are also separate closed subgroups for promoters and opponents of the family ticket. The system keeps track of the structure of these forums and informs the mother-forum if a subgroup has achieved a result.

Many participants use the search agents to find interesting contributions, but a tree of the forum structure is also offered for those who prefer browsing.
