Ah hello Harison, and welcome!
PC has loads of wonderful skins, and Let's Fly Together is a really good-looking one I have to say. In fact, you can change skins in the drop down at the bottom of the page or also in the User CP. There's sure to be one you'll love! I'm using Chromatic right now cos it's basic and doesn't hurt my eyes a lot. Is there any specific part of Pokemon you like? Such as the games, anime, TCG etc? No matter where your interest lies, you'll enjoy PC nonetheless. The two above me suggested the Pokemon gaming sections as good starting points, but we also have sections like Pokemon Trivia and Pokemon Clubs, which are great places for making friends. There's also Chit Chat & Polls, and the other off-topic boards if you ever need a break from Pokemon.
Like what AWsquared mentioned, we have helpful staff members who can assist you with any questions you have. One such person is Cirno, who mods this section, she'd be happy to help you anytime since greeting new members is her specialty. Also remember to read the rules, and if you ever need a new friend just send me a visitor message. I'm always open for new friends!
Have fun, and I do hope to see you around!
