Changes

:: About the user names with digits: I really don't like the idea, as we might lock out potential human users as well. As long as they just sign up and give up then, they don't do any harm. They just pollute the database, which isn't nice, but not a real problem either, I think. Actually, as long as they don't post anything, I don't even block them any more, because I don't think they will ever come back anyway. We might want to create a script to delete users that were never active at all after signing up or something like that. Anyone else has an opinion on that?

:: Also, I added a num-switch to RecentChangesCleanup. See [http://hitchwiki.org/en/Special:RecentChangesCleanup?num=500 here].
