Thread:Project:Support desk/How to know which extensions are used ?/reply

Heiya, have a look at WikiAPIary. This wiki collects all sorts of useful information on wikis running MediaWiki including extensions and their usage. Also, when looking at the extension's pages on this wiki you will see a little info at the bottom of the box displaying infos on the extension which says "Check usage and version matrix". Just click on it and it will bring you where some music is. :) Cheers
