Hello, Omar (admittedly I thought of Omastar almost instantly when reading your name lmao), and welcome to PC! It's nice to meet you, I'm Cirno. ^^
I wish you told us more about yourself since it'd be a lot easier to pinpoint places on the forum you might be interested in that way, but of course it's up to you! Either way, given the size of our community, I'm sure you'll find at least something you like, so make sure to stick around, yes? As Leaf Storm said, the Adoption Center is a great choice if you want a mentor to show you the ropes of your favorite section(s) and make your first friend here. <3
I noticed you've already posted in the Battle Center, that's a good start! I'm unfortunately not skilled enough to battle others right now, but that doesn't mean I shouldn't try. :3; Anyway, enjoy yourself here and feel free to contact me if you need any help at all, all right?
