Udo -- read the original post. In fact, go back and read the entire thread, you'll see this has all already been discussed. But to clarify, I state clearly that members should refrain from sexually explicit language and images. The occasional f-bomb is fine, just use it in moderation. Because what it breaks down to is this:
Our admin wants a PG-13 website so that it appeals to the widest possible visitorship. We mods are therefore tasked to ensure the content of the message boards meets that requirement. If you want to talk about tits and ass and sex and get all raw and adult-like, there are myriad other horror websites where the members are allowed to run free. But those websites also have FAR more trolls, haters and flame wars. If that's the kind of board you're looking for, have at 'em.
But here, members are expected to conduct themselves in the same manner as they would if they had a thirteen year old sitting next to them.
You don't have to like it; you just have to do it.
