Honestly I haven’t looked at the FW wiki much until I saw this thread, got curious. I only used it for getting through that text game. From what I can see it’s not MediaWiki so some of the capabilities are not there, unless the mods are just hiding/disabling them.

ED has a bot that automatically fixes double redirects, and does other things that don’t apply to this wiki. There’s a “Special Page” where all the double redirects are listed, and we used to go through and fix them manually.

So yeah, you have to keep an eye out for it and then fix it all manual-like on this wiki afaik.
