Hey there Sam! Love the Nidoking avatar, its shiny sprite is really quite awesome. I miss training one in my games. ♥ Anyways, a huge welcome to the forum!
We all adore Pokemon here so fitting in will not at all be an issue. :D What aspect of Pokemon do you like most? I'd love to know a little more about you and you shouldn't ever be shy to tell us about yourself. We have people who love the first few generations as well as members who only got into Pokemon recently, so the community is pretty mixed. Personally I'm a huge fan of the games and anime (plus the merchandise + cards as well, actually) and have been into the franchise for more than ten years. You can get involved in battling, trading, join clubs, and discuss your favorite aspect of this awesome series right here! You seem pretty enthusiastic about joining which makes it all the better, too. PC loves members who are excited to be a part of things.
A great non-Pokemon board for you would probably be General Entertainment! That'll be your home if you're interested in discussing music with other members. While you're there you can also chat about your favorite books, movies, TV shows, and even anime, making it one of our most diverse boards. If you make music yourself you can also delve into the Creative Media Showcase thread in General Entertainment to share that with us - we'd love to see it! I'm pretty strange since I'm one of the few people who don't listen to music all that much, but techno and pop are actually some of my favorites. Like Fay suggested, tell us what music you like! We shared ours so now it's your turn. Maybe you can also say what games you play? Bonus points if it includes Animal Crossing and Fire Emblem, ehe.
I'd recommend taking a look at the New Users' Hangout sometime as well if you're looking to meet other new and old members alike. You'd hit two birds with one stone if you looked around there; it's a great thread with awesome people.
Hope you have a blast on this awesome forum! I'm always here if you need someone to chat with or want help, so contact me anytime. See you around~
