Well, first you need to look around. Read the Wiki, get a feel for the setting, etc.
Then you need to formally submit a character. One doesn't just start RPing until they get a character approved. Also, it's a complex setting and some study is pretty much necessary to start. However, it's pretty fun, with a lot of possibilities.
This is a sci-fi setting with multiple factions and ships. Most ships played are military, but this is one of the civilian plots.
And good, she might make good use of the Kylie or the Enhanced Demon.
