Omg, I love your enthusiasm! Welcome aboard, Morbid! I'm pretty sure you'd be able to make lots of friends here, I doubt it if you won't since I mean this is a pretty huge community and everyone is just really really nice and friendly. Don't be shy as well, try to open up a bit, but I don't see you as a very shy person though, I see you more of an outgoing person based from what you just said. But the thing that I'm pointing out in here is that everyone is welcomed with open arms even if you're just a casual Pokemon fan or have just played Pokemon once! :P
PC offers lots of things whether that may be graphics, ROM-hacking, tournaments, trading, battling, cards, collections etc! The boards are also diverse (what I mean here is that you can come across Pokemon related ones and those that are not related or in other words, off-topic discussions) which actually makes it easier to like participate and get to meet lots of people around and make friends with them. ^__^
Have you read the rules yet by the way? If you haven't done so, then make sure to read it, I'm quite certain that you don't want to get into any trouble. I can be really scary as you can see! Kidding of course! :D .. If you need any help, my inbox is pretty much open for messages, so just contact me if you need a tour or assistance to something in here. 'kaay? No worries!
Enjoy yourself!
