There are. Now and then the posting guidelines are posted. I don't have them handy, but someone no doubt does.
The biggies are No Profanity, that one is stickly enforced. No racist posts, no inciting violence, no personal attacks. These are also enforced but a little laditude is granted since this is an adult forum. Lastly if you refer by name to another poster you should ping them to the post. Also this is a conservative forum so if you are not conservative you might get the zot. Newbies in particulars, the longer you've been a member the more slack moderators will give you, but long timers are expected to set the examble and not immune. Hope that helps.
Thanks RightWhale... I know I have looked! :)
