Hi, Nolan Muina! Welcome to the forums. As what as my friend, Megan said above. PC is a large forum, and it can get confusing. PC is diverse, so you could come across topics that are not related to Pokemon, basically it's all here, just like a coffee three-in-one! So just take your time to explore, and I'm sure you'd get used to everything here!
You joined the Snivy Fan Club, right? That's awesome, I hope you would have an amazing time discussing Snivy and it's evolution line there, don't worry too much, we wouldn't bite! :P ..
Along the way, you'd also get to meet a lot of PokeFans here and make friends with them. Don't be shy, just be yourself and you'll be perfectly fine! ♥
Also, remember to give the rules a view if you still haven't, I'm sure you don't want to get yourself into trouble, don't you? If you need someone to talk to or if you have any questions by the way, then feel free to visit my profile and leave a message, I'll reply as fast as I could! Have a wonderful time and really looking forward to see you around the board. I'm a stalker y'know? :P
