ohh, art fight is an art trading event that happens every july i think! basically there's 2 teams and you can "attack" the opposing team by giving someone on that team artwork of their character, and you can receive a "revenge" if they draw your character in return. you can also do something called a "friendly fire" which means attacking someone on the same team, which you don't earn as much points as you do on the opposing team. it's a friendly game don't worry ^w^ art fight is a great way to practice art and draw new things, while receiving nice gifts of your characters in return :D sorry if this is hard to understand, i explained this when i was very sleepy so i hope that's okay! if you go onto their homepage it should tell you how it works too
