From Cb Wiki
"CB Colosseum" (http://z6.invisionfree.com/CB_Colosseum/index.php), often abbrieviated to CBC, is a competitive Pokemon forum. It is administrated by Spire,and is populated by Smogon and SPPf members, with some other people as well. Spire has made various sites for the forum, most of them dead. The forum's current site is http://cbc.orgfree.com/index.html.
The forum is predominantly 4th-generation based, with most of the main battlers playing D/P OU often. It also happens to be one of the few places with a tier list for D/P (and one that doesn't fail moreso).
