Welcome to Star Army! My advice is to be bold, don't be afraid to try stuff. I'm looking for active, creative folks who, ideally, not only RP with other players but also build on the setting's under-developed areas and start their RP threads once they're confident they have a feel for the setting. The wiki is very thorough on making a "normal" character for the setting, I don't think you're going to have much trouble with it. If you got questions, we're here for you. The best way to have someone walk through the character-making process with you is to talk to people in real-time in the chat channel.
