i have to say, doing SW fandom has been nothing but a rewarding blast for me. i've loved every minute. even as a prequel hater, i've made so many great friends and had so many fun conversations.
i'd definitely recommend starting with your area's board at FanForce, as none suggested--there may already be something going on you can participate in, or maybe get involved in planning and helping with events.
have fun and good luck!
