I personally didn't find the OT forum posts so far to be offensive (for instance Mandy asked me if it was alright to post that one link in off-topic, and I said no problem) The level of innuendo so far is less than the typical teenage MySpace profile.
From a legal perspective, we've done nothing to require an age restriction. That type of thing implies birthday suits or very explicit language... you know, the kind of stuff kids get from TV and music already.
From a site owner perspective, I'm not going to run a site that has an age restricted forum... that just gives off the wrong idea. I'd be more likely to abandon the whole OT forum rather than do that.
All that said, we do realize that it's a family site, and we're not going to allow anything really inappropriate to go on, or allow the focus of the forum to be solely innuendo... we're Geeks, there should be primarily GEEK related content. Perhaps we'll be a little more careful with what is allowed in the future.
Rule of Thumb for Members: It's a bad idea to talk about Race, Sex, Religion or Politics, because Somebody will be offended Somewhere and then write letters to the FCC about the half-time performance.
Finally, For the love of FSM, please just email me if you have a site policy question, and let's have some faith in the geeks behind the curtain. We're not perfect, but we are keeping an eye on everything. We've managed to turn this into one of the best sites around, and we're not going to sit idly by and let it destroy itself, so you shouldn't worry.
