Hello there and welcome to the forums, Detso! It seems that your love for B/W brought you over here, if so, then you just found the right place. Hikari already introduced you to the B/W section. It's a pretty active board as you can see, you can find lots of interesting things there and you can also contribute lots of awesome stuff if you want! Personally, Unova isn't my favorite region despite Snivy being my favorite Pokemon of all time. I'm still going for Johto, I really wouldn't forget the experience that I had when I first started playing Pokemon. Was pretty amazing if you ask me and it brings back lots of good memories from the past. :3
Mew also linked you to the Pokemon Anime board wherein you could discuss things about the recent Best Wishes series. I haven't been watching the series lately, been busy the whole time so I don't have much time to watch it. But I've been following it ever since I was a child. Will be pretty much spending my whole vacation catching up. :P
There are also lots of interesting boards around so you might want to check out! With that, if you ever get lost or confused, feel free to contact Megan and I for questions and for some assistance, we really don't bite as you can see and we're really nice, so don't be afraid to approach anyone of us. In case we're both not around, you can also contact the other staff members that you can see usually those with bold usernames. XD
Other than that, make sure to follow the rules as always and have lots of fun here 'kaay? ^^
