The misspelled word "villian" (should be "villain") occurs a lot on both TV Tropes and this Wiki.
Will some admin please do a global substitution for this typo?
If we still have a page about typos, the page should of course be excluded (or rather the page should be edited to break up the word with comments so it won't be found in a global search). I don't recall if TV Tropes had that page either now or as of 2012. Also, "vaudevillian" should not be substituted. The Ambush Bug character Villian the Villain is an intentional invocation of the misspelling, but I can't find a mention of him here.
Long, long, ago on TV Tropes global subttitutions were actually done. But it hasn't been done in a long time. Surely we can do it here (upon manual intervention by an admin). At least there should be a thread for typos where people can post common typos, and admins could look them over and decide which ones are common typos and can be globally substituted without messing anything up. There are a lot more than just "villian"; it's just the most obvious one.
