Your avatar is so precious. Oh how I want to hug little Piplup. <3; Welcome to PC, Iny Gage!
Roleplaying's fun and quite popular here so make sure to give our Roleplay Corner a look-see; you'll find a lot of both Pokemon and non-Pokemon roleplays there! Just remember to read the section rules as well as roleplay etiquette before making any posts - they help outline how everything works here in regards to roleplaying. Luckily they're simple to understand so I'm sure you won't have a problem. ^^ But in the scenario that you are confused, just send the section moderator,
Skymin, a private message (though the forum regulars are also very helpful and always available to point you in the right direction, too).
Aaand for all team-related assistance hop on to the
Battle Center! You can create a thread in the Competitive or In-game Team Help subforums depending on if your team is competitive or not competitive. The Battle Center has plenty of talented battlers and events going on rather often, so it won't be long before someone stops by and helps you out. :D If you're interetsed in battling, maybe you can join our Pokemon Showdown server sometime, yeah? You'd be surprised to see how many amazing regulars the server has and they appreciate every new member.
Enjoy your stay and great meeting you~!
