Uhhhhhhhhhhhhhhhhhhhh, I'm with chris... Which site exactly?
*EDIT*
Ok, there's an IP address on the Black Ops poster, which takes you to a site run by GameStop. You can enter your email to be sent an email when it's up. Actually, it's believable. I'm entering my email. Maybe everybody that signed up get into the beta? Who knows. Heres the ip address (If I can?)
