For roleplaying, we could hold some events in dA chats, such as gatherings? We could also upload pictures of different places into the gallery, then in the artists comments of each submission we could describe the setting, then let group members roleplay in the comments. ;o To start the chain, an admin could post a roleplay, and then users could reply. HOWEVER, that could get mighty confusing in the comments section. A forum box on this page would seriously be useful, but I don't even think super groups have that.
I could always make a seperate forum as another website, then we could put it on the front page of here, telling people to go there to roleplay? Gatherings could be held in a chat room one of us makes, and the submissions could be of people's cats, their cat artwork, roleplay logs, etc.
Just some ideas I decided to get out there. c; Hide this comment if you don't want anyone coming to this page to see.
I personally believe that before we decorate anything to appeal to potential joiners, we need to have something organized for the joiners to do once they join or else the group wont go very far.
