Great add-on and great developer, very responsive and professional!
I funded* this add-on, because there was no social groups solution, that was suited for a big community and met our needs.
This add-on was built with XF-standards and performance in mind. It is important, that it does not use the node-system for the discussions of the groups, because XenForo’s node system is not made for thousands or more nodes.
* I funded this add-on, but I am not involved in the sale and don’t get any revenue.
