@Xenon: S/he was asking if the hacks were available, and if they were s/he'd sign up on March the 5th...
@Bluecougar: You want to use logo.gif as a forum icon? That's more than possible

. The download center is attachments I believe (you can attach files to posts). You can't attach files to a download centre though. But this is possible, as is many things with vBulletin.
And as Dpcows said: There is a photo gallery a calendar and a quick reply (which is the hottest hack on vBulletin) out already.
The support is very good, and all questions sent are answered in under 24 hours max of the time.
Hope this has helped you make your decision

PS: Oh and your info is processed quickly. If you're sending a check (as I did), it takes about 4 days to a week max to be validated and accepted/declined. I got my email within 3/4 days of sending I think.
If you sign up with a credit card which is valid, your order is validated and accepted/declined immediately I believe. And if it's not immediately, it's within a few hours.
