What they said.
Only thing is that the "thePokéCommunity" link/banner that follows when you scroll down already links to the index page so I think that instead of "HOME" leading to the same page, it should lead to the User CP. I want to reach the User CP much more often than the index page, and like I said there's already a link to that with the banner. I think most people know that a forum banner usually leads to the index, too.
EDIT: oh right. There's that menu line at the bottom of the screen, with a link to the UCP. I forgot that :3 But still.
Also, the faded area below the black scrolldown banner makes things under it unclickable, which is a tad bit annoying. Maybe the faded area could be shorter?
