Topic on Project:Support desk

Extension:StructuredDiscussions is used by MediaWiki to create the Support desk.

The Discussion page of Support desk uses a redirect.

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?

Extension:StructuredDiscussions

The discussion page peculiarity shouldn't be a bug, it has a redirect link to this page, although am not sure why the redirect link works here slightly differently than normal.

Understood. Thank you so much.
