Hey, welcome to SWRP!!! If you need any help, just ask. I can help to the best of my ability. I think the first thing to do is post a profile for a character.
Copy and paste the basic Character template into your post and fill it out. As long as you stick to the format, it should get approved. Just make sure everything is filled out. Also, ensure that your character has no reputation. For example, don't say "he's a famous crime boss" or something of the sort. Sticking with that analogy, he'd be a "small-time street criminal." Make sure to link your tech.
Furthermore, if you do get something wrong, no sweat! The mods'll help you work through whatever quirks you might have.
