How to create forums like this MediaWiki Support desk?
In other words what extensions, templates, etc. MediaWiki uses to create this Support desk?
I tried to find related extensions in the Special:version page of MediaWIki, but couldn't find anything. Another problem I noted is that when I click the discussion link on the support desk (Project talk:Support desk) it opens the same topics posted in this main page (Project:Support desk). Can someone please tell me is this a bug?
