You and your wiki have come a long way. You know it has seen good times and bad times, sometimes many contributors where there, sometimes there where only a few.
If you feel like sharing the history of the wiki with the rest of the readers, use MediaWiki:Aboutsite.
It however normally is not in use. Linking to it from pages is needed to get people their attention towards and this page is not self updating, so you will need to update it if you want to.
