Art-wars conducts online art contests and photo contests for money, and members vote on the entries for a cash prize for the winner.  Contests are open to all ages (you’ll need parental consent if you’re under age), and open to anywhere in the world where you can send and receive money via PayPal or credit card. Some other means of award payment are possible as well.
New contests are usually posted on Fridays at noon, Pacific Standard Time (19:00 GMT), and rules are posted in the column to the right and sent via email. Contestants can then check the clocks at the bottom of the homepage to see how long they have to upload work. Voting by any member starts after the upload period, by going to the Current Entries page.
