if you want to post a Request thread, where people go and ask you to make art for them, you can make a thread and call it [Request] (your name)
and show 3 examples of your art and a form where people can ask for art.
You can also make a Commissions thread, where people are willing to buy your art for money, or in-game coins, or currency from another game that you might play. Kind of like the Request thread, you need 3 examples of art and the amount of which it is being sold.
