Bummer. You have my condolances. The folks here on rec.woodworking have decided that putting up with net nannies/control freaks is worse than the occasional off-topic thread - and one of our regulars maintains a filtering package for those who'd prefer not to see the OT threads (or the occasionally really nasty garbage posts) at all.
Normally (but obviously not always) we add "OT" to the subject to facilitate filtering, and it works fairly well. RW (the "wreck") is a fairly convivial group - and occasionally the people who've gotten to know each other here do enjoy OT side discussions. The antisocial types who pop in and object are generally held in low regard - the wreck values right answers, but not people who're all about _being_ right.
I'll gladly trim RCM from my future responses. :-)
