Where are you from? I'm sure there are also other members here in PC which has the same location & nationality as you! I'm a Filipino and I've met several great fellow Filipino members here as well, one of the reasons why I love PC A LOT! Welcome aboard, anyway! I'm sure you just fit in fine here, plus PC has a very friendly atmosphere & all, so don't worry about making friends and talking to anyone of us, we don't bite!
In regards with PC, well, all I could say is that your gonna have a lot of fun here, basically because of what PC offers, first, fun & exciting discussions, yes, the discussions here aren't just about Pokemon and all, while discussing you could also make friends with others! Second, if you ever get bored of Pokemon for a little while, then PC offers you the off-topic discussions! Such as the Other Chat, Other Voting Polls and a lot lot more! In which obviously, you could join topics & perhaps make your own as well about things related to life, and everything not related to the whole franchise! :D ..
There are still a lot more to explore, but I wouldn't just tell it off to you, it would be really fun if you could explore it yourself! Go, start your journey now, my fellow trainer! :)
