Am I the first person to post on vBulletin?
Yes, you are, since posting was disabled out of the box for several hours. I've just now fixed that.
Hrmph. This is going to be definitely be a nightmare to configure at first. When and if it's all set up, though, it should be nice and smooth. But expect lots of bugs and weirdness in these first few days.
The incorrect "last visited" date is another weird artifact of importing from UBB. But I expected lots of weirdness, so I'm not really surprised. So far, it's actually not QUITE as bad as I feared it would be.
