Wikichan

The mascot of Wikichan (a parody of Wikipe-tan)

Wikichan was a wiki dedicated to 4chan and imageboard culture in general that existed a few years ago. /tg/ typically used the site as a writefaggotry depository. The site's history was somewhat turbulent - at one point it was offlined by hosts for displaying personal information about Hal Turner, and it suffered at least one major database loss - and in the end it disappeared mysteriously with the primary admin, WikiSysop, never heard from again and no backups ever seen, all of which happened (relatively) long before 1d4chan's time.
