There would have to be some regulation there, too, and careful watching.
Since there is not a mod there at this point then I should probably not try such an idea right now...
I'm pretty sure we can have a group for more than one thing... I mean, the Rocket fanclub began more for Jessie, James, and Meowth, who are all individuals and could probably have had their own specific club. But eh I guess it is up to people who know of such things.
