Oh wow you have been into Pokemon for a while, but don't worry about your age because we have a lot of older Pokemon fans here at PC itself. But hey, nice to meet you Dave!
As Zeria said, why not tell us more about yourself? We'd love to know you so we can recommend potential favorite sections for you. It's always good to tell us as much as you can because well, someone may share interests with you and that could open up potential new friends. Given you got into Pokemon during your teens, I assume you were a late bloomer but I had a similar thing happen to me, since I was 11 when I first played a Pokemon game.
Well, have a great time with us and if you ever need anything don't hesitate to contact either myself or any of the staff members! Do stick around if you can.
