Hello there, Darkrai 16! Welcome to the forums. Don't worry, I think most of the members here loves Pikachu including myself, I mean what's the thing to hate about it? It's absolutely a very cute Pokemon and definitely needs lots of love and attention! I wish I could get myself a very huge Pikachu stuff-toy someday! :3
.. Anyway, we're really happy to have you here and it's awesome to have siblings around the board. <3
I'm pretty sure you'll be able to meet a lot of PokeFans here and possibly make friends with them as you keep on joining discussions and stuff. Don't be afraid to talk to some of us as well by leaving a message on our profiles, I mean what's the use of the visitor message system if it's not gonna be used as means of conversation? Plus, we really don't bite and I'm sure your brother knows that! :)
I don't know what your interested in since you did not mentioned it, so I can't actually give you a little tour. But really, there's basically a lot of things to check out, and a lot of sections to visit to! So just take your time to explore the whole board it might be confusing at the start since it's really big and it would take a lot of time to look around, but it's definitely worth it if you'll get eventually used here, right? RIGHT?
Have fun around and make yourself at home! Be sure to read the rules if you still haven't done so by the way, it will keep you away from troubles and the like and I'm sure you don't want to get punished or something? The staff is really scary but they're nice and friendly if you follow the rules all the time, so make sure not to get 'em mad! :P
