I answered the question you asked over in the New Users Hangout, so do go see my answer if you can. Aside from that, we're really excited to have you here Sceptile!
I do have to say, I'm in love with the new-look contests in OR/AS, especially now that your Pokemon does this really awesome animation (based on their type) when they max out the audience's excitement. Sinnoh's had an interesting format, but I can easily see why some people didn't like those as much as the ones in Hoenn. Anyways, I'm sure you'll be enjoying whatever topics interest you here at PC since there's so much you can do here.
Well, I wish you good luck with your journey around PC and I hope that no matter who you get as your Adoption Center mentor you'll definitely be in to learn a lot from them nonetheless. See you around the forums and enjoy your stay!
