Firstly, that new blue background you added , in the admin cp where you enteredthe URL for the background tick the box underneath it and save. It's called fixed background
second, create a help and support section so I can post stuff like this in there as it's not really for a suggestions section
EDIT: hang on have i just suggested something that is already here
was the background fixed before? or have you done it from my suggestion? i was on my iphone earlier and sometimes things arnt how they should be when viewing it on there.
and also i just noticed there is already a support section :)
BTW: this background looks loads nicer than before, remember sometimes simple is best
