Well, Welcome to the Freedom Fighters! I know, not a big club now, but sooner or later, its gonna be just as big as the regular Sonic Fan Characters Club. Enough with the intro. Now, what members (fans) can do here is almost unlimited. You can create defense lines to a certain extent, if any enemies get within the club, defend. You can also make fan art if you want. Images of the members, or a group picture, participate in contests, create roleplays, (i base rps into comics, im pretty sure others do similar so :P) to me, the list goes on and on as the days go.
For now, I'm going to keep this short and sweet. You can do pretty much whatever. Well, as long as its not rated too bad.
