Hmm... Im not sure the background works. I'm going to change it back as the one we had was ok. Good Job with the admin names however. Could you tell my how you did it for future refrence?
If possible could you create a post with screen shots of you wikia theme suggestions and then create a poll or vote that we can vote on. a bit like what i did before i moded the LBP wiki. I might of mentioned this before on a different conversation but untill the game is released it might be a bit hard to find the perfect theme to match with the game.
as for future background tests, could you find a image that really big and will fit the whole of the background?
