If you want tons more advice and wish to become more active in the community, then I would go sign up here on the offsite:
http://s3.zetaboards.com/BuzzerBeater_USA_NT/index/. Once you do message
(23075) and tell him that you need your application approved. On the offiste, all of the really great mentors and player in US BB hang out, talk about National Team strategies and are always willing to offer great advice. Stick with the game, it takes a lot of patience, but it's really cool. Hope to see you around!
