1000th Member Here
Member numbers actually still exisit... but they are just used so the database can store them. Look at anyone's profile and you will see something like userid=1000 in the URL.
The display of numbers was a feature of the UBB. vBulletin does not use it. I never really liked the Member Number display anyway, it kind of made it seem like you were ranked based on your member number.
Eh, sorry to burst everyones conspiracy theory. Please continue on as per normal.
