DOs:

DO be in character when possible. A little talk between admins is good, but when your character is basically you yourself with the pp of your character, then that's when your DO becomes a DON'T.

DO stay true to your anon.

Every time you type a message, DO ask yourself: "Can I imagine my character doing this?" it will help a lot.

DON'TS:

DON'T change your character (or, if it's a cartoon character, a live-action person) and give them a new faceclaim and pretty much destroy who you're RPing.

If you're playing a villain, DON'T make them friendly, popular models.

DON'T complain about being single. People will see it on their newsfeed and be like, "Ew. ____ much?"

Uh that's all I can think of for now. :3 More coming!
