Ohaii, Helmet! :'D .. Welcome to the forums! Glad you decided to join after lurking around, so I'm quite somewhat sure that your familiar with some of our sections here. :) ..
Anyway, as what as Meganium90 said, there's the Trade Corner if you want to complete your Pokedex, breed Pokemons, or perhaps just talk around there about stuff relating to this! Aand this is kind of random but, try to check out the Pokemon Groups as well! You can join clubs there to discuss about a certain Pokemon that you joined to! /random XD
Don't worry about making friends by the way, I'm sure you will get along well! If you have any questions, go to my profile and leave a message! I'd be happy to help you out! Have fun and follow the rules as always! See you around ~
