Welcome aboard, Hikari! We're really glad to you have now become a part of this community! As what as the people above me mentioned, don't worry too much about your English, as long as we could understand what your trying to say, it's absolutely fine. And I'm pretty sure you'd improve along the way! English also wasn't my first language, but as I keep on participating on forum discussions and stuff, I'm also learning more about the language, one of the advantages of social networking sites! :P
I've been a Pokemon fan ever since, my favorite Pokemon includes Snivy (yup, obviously) alongside Togekiss and Raichu. Eevee also is in my list, yes I do have a list and it's pretty long, and I'm sure you don't want to read such long list! If Eevee is your favorite Pokemon, then what's your favorite Eeveelution? Mine would probably be Glaceon, I love it's elegance and strength, plus Ice type is really something that shouldn't be underestimated! tehe;
PC is a large forum, so it would take time to get used to pretty much everything here, but one thing is for sure, if your looking for a Pokemon forum, this is the place to be! You could come across discussions starting from Pokemon-related down to off-topic discussions, in other words PC is diverse! You could also possibly meet Pokefans and make friends with them along the way, isn't that fun? :)
At the moment, PC is hosting it's holiday event - The Holiday Hop, it's just below this very section. I'm sure you'd find something interesting there to join to, the whole community is definitely looking forward to see you around the board.
We really don't bite, so stay calm! The only advice that I could give to you is to follow the rules all the time, if you do, then you'd be just fine here, if not, then you'd get yourself into troubles, and I'm sure you don't want that right? .. With that being said, if you have any questions, feel free to send me a message and I'll try to reply as soon as possible. Have a wonderful time here at PC! Lovelots! ^__^
