Woah, really? Try auctioning it off in Russia. As of few years ago the going rate for 4 digit UIDs was in tens of thousand dollars.

My 4 digit /. UID is also prime. Does that command a premium?

So is my 1 digit UID.

No doubt that is crazy, I created an ICQ account back in the 90's, and used it probably 2 times, maybe I need to go digging through my old email archives to dig some of that stuff up, I don't know if it is a low number, but they where not around long when I created it, I remember that much. It seems strange to me to pay that kind of money for just a low number. Whats the deal, does it give you some kind of street creds or something. I have been on Skype since it came out, 2003, if I recall correctly, so I am not too up on things like ICQ numbers being worth money.
