The menu is the same everywhere, but everything else is still quite disjointed.
I don't mind the new menu, its order just seems a bit unintuitve, but that's just because I'm used to a different order; I can get used to that. What irks me is the two menus in the forum, there must be a better way to integrate vBulletin with your menu?
Like I said, the menu unites everything, and I like it better than the one on the main VC that requires me to scroll right, but everything else still has its own color scheme. The Gallery has the menu, but everything else about it is still different. You have two different multimedia sections, depending on whether you launch it through the forums in the main VC.
Basically, you have a whole bunch of stuff that's difficult to integrate into one, because it was all designed differently. For ease of use, you may be best keeping it "disjointed," but it's difficult to say until I could see the main VC and forums look alike, because if you can make them look remotely alike, then just adding the menu may be enough for the rest of your stuff.
Appanah hit it on the head when he said it was your site and you can do what you please, but those would be my thoughts. By the way, thanks for fixing the chat room.
