Ya know...

If the mods would just lighten up a little the boards would go back to normal.
I have been on various boards covering many topics for years, probably more years than some of you been alive. Anytime a board gets popular it brings in some smartasses that just want to have fun. When you try to stifle them they will try harder to buck the system, after all that is human nature..more you try to tell someone no the more the want to do it. If the mods would just loosen up a bit the board will right itself after a few weeks. No one comes here unless hey wanna lose some weight so by default the conversations will gravitate back to that topic if allowed. The more you lock, delete and ban folks the more you give them other subjects to talk about. The last fitness board I was at went through this same issue, some folks are just more outgoing than others. Make a chit chat - enter at your own rish section then. Of course posting desparaging things about others members should always be discouraged..but the sexy stuff..why not. We are all adults.
And the mods abusing their powers is really a bad thing, you are fanning the fire by being petty or self-rightous. This board is not your playground, it is the communities. If you are a mod you need to adapt to the community not the reverse, more so if you are claiming a religious aspect to your nature. And if you can't do that due to your personal beliefs then you should re-consider being a mod on a board where adult talk could happen. People lose weight here and say things to encourage themselves and others. The most basic aspect of that is sex. Sure some lose weight for health reason, climbing those stairs and such, but the majority of folks lose weight to look hot, and as they do it is natural for some talks to turn sexy as they begin to feel sexy about themselves. Why discourage that? As long as it is not blatantly x-rated then all should be good.
But, this is someone elses board and they had a vision for it, and I respect that. Just be aware though that sometimes visions have to adapt and change (see myspace).

That is all.
