When I moved to XenForo, I was really sad to leave behind the groups functionality. With more than 5,000 groups created, and 2,000,000 messages on it, it proved to be a valuable asset to my community. I used the groups to banish all those offtopic and playful threads and keep the forum serious, people use it to organize small events for which I would not create a forum, and fans talked about their favorite shows in a forum that had no room for a sitcoms category. So, I embarked on the quest of making a drop-in replacement for Social Groups, something that is not quite the functionality of the forums, but still has groups, threads, members. After a while, I am done. I bring you: Social Groups. Some features: Members can choose to create a group in any of the admin-configured categories Members can create either public groups, moderated groups, or invite-only groups Privacy options to set your memberlist, threads, posts or whole group private Multiple leaders (owners) per group, group can be transferred Members can start threads in a group. A thread can have any amount of messages. Group leaders can customize their group with color, an icon, and a group page Integrated into the XenForo experience (News Feed, Alerts) vBulletin social groups importer included I am making this available for $40. I am using it on my site and not a week from released I have a huge list of feature requests. I am sure you will have your own suggestions. I will provide updates for one year which will give you access to any changes I do. You can see the demo site, here: http://xfaddons.com .
