This was the first hockey board I started posting at regularly, a few years ago, but sadly you couldn't find a thread that wasn't hijacked by trolls. In addition, people who would normally talk some good hockey talk would usually get sucked in by one of the multitude of trolls, me included. Some people around here are pretty proud of their ability to "own" other posters in this respect. Congratulations to them, I guess. Consequently a lot of people have left, so there is nobody left here for the trolls to rile up, and things have slowed down.
If you want some serious hockey talk, check out hfboards. A LOT of threads, and decent team forums as well, depending on the team. It can get childish there, but there is better moderation, so things stay reasonably under control.
The "other board" is a little more relaxed, a mix of good hockey talk and OT threads. If you're interested you can PM me. If you go there just to start *(#$ or rehash lame Crosby/Ovechkin arguments you'll probably get banned, but hey, if that's what you're into, might as well stay here.
Between those two boards you can get most of your hockey fix, hope that helps.
