Groups are now implemented, although group IM and other features are not fully working. Please do not create obscene or inappropriately named groups. We reserve the right to remove groups or restrict their creation, although we do not plan this.
It is not currently feasible to implement the missing features, though we will do so in future when made possible by new software versions.
The long-standing problem with group chat is resolved so long as members in ALL roles are set as visible by the group owner or administrator. Otherwise the group chat simply won't work. This is a known bug with the XmlRpcGroups module.
