Walkypedia

Walkypedia! is the searchable wiki knowledge base for Roomies!, It's Walky!, and Shortpacked!. Those are webcomics by David Willis.

Willis started the original wiki (circa 2007). Yes, this means Walkypedia is official and condoned by Willis. Walkypedia was offline starting mid-2011.

Wiki was resurrected (apparently without Willis) circa July 2013.
