I'd like to suggest some ideas for future releases:
1. It would be nice, if there were an integration with current version of Eventlist, so groups could create their own events.
2. Why not let different groups cooperate with eachother? They could share bulettin messages, events and a forum in kunena.
3. I don't like, that everybody can invite new members. I think, the groupadmin should choose, who can invite new members.
Regards,
Camee
