It is a MediaWiki-style wiki created to serve as a general wiki for communities it is affiliated with (so far #zanzibar, #FMSanctity, and Gikopoi, if enough GCLF people go there GCLF will also be in this list) and as a wiki for two things: the Mega Crossover universe known as Infinitysphere or Reality 0 collectively worked on by anyone who wishes to contribute, and the other realities/universes that contributors have thought up.
The site seems to be pretty successful so far, unlike with Malachite Faction Sanctuary.
Also, Gammapedia is being moved onto Infinitypedia, I believe.
