Making a character and choosing a faction (Jedi, Republic, Sith) would be the first step. If you have specific questions that you need answers to shoot me a PM and I can help a bit more. c:
Welcome to site. @Padmé is a great reference for starting out. I can help with questions pertaining to the factions and @Clayton can answer any questions pertaining to tech. And @Green Ranger loves it when members ask him where babies come from.
Assuming you saw and read my note in your forum in box, you should be good to go. If that's not the case, and you're still uncertain about the forum, tag me here or send me a message.
