The two sites I recruite from were two sites I frequent for SF4 information, but had never posted on.
Street Fighter 4 Forums.com - http://www.streetfighter4forums.com/
Shoryuken.com - http://forums.shoryuken.com/
So far, 7 players signed up from SRK.com for Week 10. I have another 3 or 4 players waiting to join for Week 11. Thanx to all the new players for joining and we hope you have fun. That being said, PLAY YOUR MATCHES OR I WILL KICK YOU A$$ OUT!
Good luck to all.
