Already posted this to GFreeman, but no reply... so if it seems familiar, that's why ;)
Special:WantedPages is riddled with pages that only appear due to the link in "welcome to the wiki, thanks for modifying [[No Longer Existant Page here]]"
Anything that can be done about that so we can actually use it to find valid red-links?
Hey, thanks for the reminder! As of now, the deletion category should be sparkly and clean; all of the pages and files there have been dealt with appropriately.
Still quite a number of links to go in the Special:WantedPages, but I will keep working on it.
Edit: I decided that for some of the more popular missing links it would be easier to just create a redirect page, rather than delete each link individually. I should be able to get rid of the more common pages fairly easily.
