Ha ha, Pichu is definitely is one heck of a cute pokemon! Certainly one of the cutest, imo. <3
And as I can see from your intro and your signature, you seem kinda intimidated. It is all natural to be intimidated if you just became a part of such a big family. Things aren't really easy when one is new to something and I can totally understand that. But yeah, don't you worry and try not to be too hesitant. PC is a pretty nice place and I'm sure you'll get used to it pretty soon. So yeah, for now, just chill and relax. And if you aren't really sure of posting and stuff, you can always lurk...lurk like I do. XD;
Anyway, welcome aboard S.S.Pokecommunity, my friend! Be sure to read the rules and FAQ as they're absolutely essential to any newbie. I'm sure that you'll find them helpful. Hope that you have fun. So, see you around!
P.S: If you've got any questions related to PC or anything, don't hesitate asking the staff memebers. You can always approach Hiidoran, the moderator of this section. He's kind and helpful and won't really deny helping anybody out. And just in case you need me, hit me up with a VM/PM or something, kay? ;]
