You are allowed to resell it once. You have to contact them to change the contact details, address, phone etc. they usually do it within 2 days.


If your wondering how I know - I've sold mine before.


To OP: Go to webhostingtalk and sell it there. (You need 20 posts first, but they have lots of viewers and people interested in buying vBulletin licences.)

HOWEVER, vBulletin 5 is now out, so if you have a vBulletin 4 license - it's not in high demand anymore.
