Now these are all pretty obvious.
1. No porn or sexual photos of ANY kind.
2. Keep blood, violence, and gore, to a minimum.
3. Don't steal art, if I find out you did then BOOM perma-ban.
4. No sentence "jokes" (Like 'I like pie').
5. Emote and text art don't count, don't even attempt it.
6. No posting links to your website with art, or posting a YouTube thing.
7. No links to your website, most of us don't give a dam-a-diddly-doo about your work there.
By the way, use common sense and don't do anything you wouldn't do elsewhere.
