I'm gonna narrow some down. Since this group is getting bigger, I have a few down.
1. Try not to bash out other members here.
2. Keep each post appropriate.
3. Be respectful.
4. Don't post inappropriate pictures or threads.
5. Don't use bad language repeatedly (Sure, it's okay if you say some every now and then, but if you keep using them excessively. that's a problem.)

Sounds like what I'd write. Thanks!
