0. Follow the Gaia TOS.
1. Nothing over PG-13
2. Nothing especially offensive to any race, religion, sexual orientation.
2. Don't insult other people's work.
3. You can politely suggest that they could improve in certain areas.
4. Respect each other~
5. Don't be a loser. Meaning, if someone's saying that you need to work on your spelling, then don't take it as an insult. Believe me, we were there once.
6. Try to be literate. Unless a character is speaking, or has written something. Then you can use all the 'made up words that just happen to be in the dictionary' you like.
7. Don't use French. I'm kidding. But seriously. Characters can curse, but in descriptions--it's annoying.
8. Said curse words are also annoying when people from ancient times are using them--guys, they didn't have swear words back then. Get over it.

Failure to follow said rules, will result in an unhappy Thali.
