I have been a member of bowlingchat since April 2011. It is the most informative bowling forum I have found. I've learned more in the past 2+ years there than I have learned in over 20+ years of bowling. Included in the forum is a Wiki section with the most up to date bowling information available. Also included is a coaching section that is simply amazing.
People without a lot of knowledge need not apply. This site either ignores or makes fun of those who do not share their wisdom. It is a shame that as smart as the administrators are that they would make a mistake like this, which limits them to the veteran bowlers and beginners, well study up, then maybe come back.
This is a bona fide Bowling forum. I've been visiting for several months.
The site is well monitored for content and is basically a no nonsense forum populated by earnest folks.
This is a very good forum for learning about many facets of the sport.
The major anchor-man or attraction is the affiliation of industry stalwart and innovator Mo Pinel.
At this point, this is the best web based forum for learning and exchange I've encountered.
