[Esorcista]

Hello! :)
My board is at http://www.aomitalia.com/forum.
I need some help for the layout
How can i resize my forums?
I use 1280x1024 resolution and it's ok, but in 1024x768 it show at the bottom the scrollbar (bleah).
Tnx in adv. ;)

You need to edit the header template for the style that has the scroll bar, the image you have at the top is just a bit to big ;)
