Jesus, are you Free Software fascists done yet?
The people who wrote vBulletin do, unfortunately, seem to be a little more concerned with Windows than I'd like. The docs keep showing Windows screen shots, even though they're written for both UNIX and Windows. Maybe that's because Windows "admins" are likely to be considerably dumber than UNIX admins (otherwise they wouldn't be using Windows), but it is annoying, certainly.
I didn't pick the Linux distro on the server. Hell, I'd rather it be running a *BSD (which, by the way, the mail server is). But you don't see me bitching and moaning.
Man, I'm glad I have Refalm to absorb most of this whining before I even see it . . .
