Category:Founded in YYYY

This Founded in YYYY category here on WikiIndex is for those wiki sites (along with wiki engines and wiki farms) which we are unable to determine their foundation date, or have not yet checked said wikis to establish their year of foundation.

To determine the age of a wiki

• The founder of a wiki probably knows its age;
• If they are running MediaWiki software, there are three ways:
  • Go to the 'Oldest pages' at /Special:AncientPages for the wiki and look at the date of the first article (note that it lists pages that haven't been edited in a long time, not the oldest pages overall);
  • Go check the date for 'MediaWiki default' at /Special:Contributions/MediaWiki_default made its first contribution;
  • View history for a system message (as found in the 'MediaWiki' namespace – search in Special:PrefixIndex), and check when MediaWiki default first edited it;
• For Wikia wikis, the exact date of founding used to be available at /Special:WikiStats – this feature is now defunct, so follow the above MediaWiki advice;
  • Wikia 'MediaWiki default' is found at /Special:Contributions/Default.
