If I edit anything more significant than, say, removing a category, I go to a blank page with the URL having action=submit added to the page name. The edits are still saved, so I shrugged and kept going.

It sounds like you're having some kind of connection issue.

While we're on the subject of the wiki, though, could I ask you to please stop editing for matters of simple word choice? One of the first things I learned in my editing internship was never edit unless you can back it up with the rules; you let the author use their own voice as much as possible. For instance, on the Mary Sue page, you recently changed "does not" to "doesn't" and "there's the rub" to "there we have the main problem". The first change doesn't do a thing to aid clarity and actually de-emphasizes a statement I was trying to emphasize, and the second merely replaces an informal turn of phrase with a formal one. Not only are those kinds of changes unnecessary—the first in particular, and the second because PPC Wiki should not be as dry as a textbook—they're also mildly insulting when they're done on pages I wrote. I know I'm not perfect, and I don't mind edits that improve clarity or straighten out backward phrasing, but editing simply because you would have used different words to say the same thing is not cool. Please don't.
