Only Sonic

I've noticed there are about 5 or 6 Unions associated with sonic the hedgehog (all of which im in), but thats it. Is anyone thinking of maybe a Knuckles union or a Miles 'Tails' Prower Union? I'd set one up myself if I hadn't already got my own union ( http://www.gamespot.com/pages/unions/home.php?union_id=RSSoG ) but i'd happily join a union like the ones I have just mentioned. I know there is a Shadow union but thats about it
