Hello, John! Welcome aboard, it would be really nice if you could tell more about yourself so that we'll be able to offer you the best things here in PC, maybe like, your interests? What your looking for in a forum? What are you expectations to the members, and so on! If you don't want to share anything though and would like to keep yourself mysterious and private to the public, then we'd reconsider. We're still happy to have you here anyway!
Basically, you could find a lot of things to discuss here, starting from Pokemon till' topics that aren't related to it anymore. You could also get to meet the whole community and perhaps make some friends. It's fun!
You could ask anyone of us, we'd love to help you out! So don't be afraid to ask if you have any concerns about the forum. Other thaaan that, have a great time and see you arouund~ and yes, beware of me. I'm a stalker. :3 .. no, not really, kaaay~
