Can now join apparently?
One of the deviantart changes automatically made it so that no one could join, and I have fixed that. There are a lot of odd new settings for groups that I currently don't have the time to explore so any ambitious members please PM me and I'll add you as a co-admin. Then you can help migrate deviations and navigate the interface I don't have time to learn at the moment.
In a few months things will clear up (I hope) and I'll be able to take some steps in navigating the interface to the benefit of all.
