My guess is that it is not possible.

What I have seen that has made me look twice though is one user trying to imitate (Harass) another user. They came in with the same name and country but with one letter in the name, looking the same but slightly different. From memory they were using a "1" (one) instead of an "l" (Small L) or something similar.

My guess is that this is what you saw in this situation.

u can play 2 tables at the same time... 2 or 3 monitors would accomplish this... I have done it with just one monitor... you have to be quick though
