[sighing patiently emoticon] When the 2000th user registers we will have 2000 registered users*. If we were counting years we would have to wait for the 2000th year to be over before we could say that 2000 years had passed since...

*We have to wait for the 2000th user to finish registering before we count that lucky individual.
