Heeey Panda! D'aw, those guys are one of my favorite animals. Welcome to the community!
It's cool that you want to get more involved in this place; there really is a whole lot more to do here than download hacks, after all, so participating more is wonderful. Maybe you can join some clubs or play forum games? We can always make some suggestions for you if you like so don't hesitate to ask! Discussing X and Y is really popular around here at the moment so that's always fun too.. I'm pretty much all over the place myself since there are a lot of cool topics to discuss nowadays. :o You'll find lots to keep you busy!
Have a lovely time around the forum and I'm always here to lend a helping hand if you're confused. The community is huge, after all, so don't worry about ever asking questions and the like. Our moderators are thrilled to assist. :) See you around and welcome once again~!
