The best way to get your feet wet is to just jump right into an open Public thread and start writing. That's what I'd recommend. Public threads are a great way to meet new people and get a feel for your character at the same time.
Or you could always post something in the Roleplay Discussion section if you have a specific story in mind for your character. I'm sure that there are others also looking for threads who would take you up on it.
Lastly, if you join a Faction, there are Faction threads you could jump into.
Chaos is pretty friendly to first time RPers. You'll do fine
