The Simming Encyclopedia, often abbreviated to SimEnc, was a wiki for recording online simming and roleplay history founded on September 2005 and run by the Simming League. From 2005 to 2012, it functioned very much like Wikipedia, and championed collaboration, and consensus-based decision-making among users.
In late 2012, its editorial board made drastic policy changes, a major one being that editing pages was restricted to people standing close to the subject, such as game masters and other leading figures of a textual roleplaying game. This however resulted in a conflict of interest of the people editing articles as well as a decline in user participation. The collection of information and creation of new pages stagnated.
SimEnc migrated to Wikia in 2013 and merged with two other wikis of a similar topic, becoming Role Play Wiki.
