Okay guys, i'm just gonna say it now. I don't like Original Characters.
...but i know others do so i'm not gonna be a jerk and not allow them. But i ask one thing. Write us something about them. Tell about what they look like and there personality and who there related to, etc. Also, don't just come in and say 'Oh well my OC is best Friends with RKarkat' without consent of the roleplayer playing that character. Also, don't get mad if people do not know your character atau do not get all facts about them right.
