Hello :D I'm Kjt. I'm also on Serebii and Mt Moon Community. I write fanfiction. If ya want to read it, click here. I'm currently attempting the postgame of White, and I'm having trouble accessing the Dream World XD
The first booting of Dream World is really wonky for a lot of people, once you figure it out it really opens up to a lot of very nice features, like berry growing! hehe.
Enjoy the post game content, there's a lot of ridiculously powerful trainers out there... a particular champion especially.
