Hard questions. Some wild guesses. I had to restrain myself from checking them out. :-/

1. StevenT? No idea. I can't remember any non-US/EU ones.
2. Link (J2HG)
3. R3p and SkulL
4. ShadowGPW and Moonblaze
5. I can't remember the winner, so I'll go with uh... FoR and TF
6. R3ptile No idea. Oh yeah, what ZippeR said.
7. Bobby and Syntax? Wild guess, since it's a tourney.
8. Huh? It actually started? So, um... Stripe and Bobby?
