Need a little help with template

[Serenity]

first, it looks like there is an issue with your margins
go into
admincp>Styles & Templates>Style Manager>All style options (of the style in question)
scroll down to Body
look at the box that says Extra CSS Attributes
see what the margins are. i'm sure you will be able to push it left with that...play with the numbers a bit till it lines up right. there should be 4 sets of numbers in this order
top - right - bottom - left
so i'd have to say match left and right and it should fix that issue.

as for the space above the footer nav bar
go into the footer template and search for

<div align="center">
 <div class="smallfont" align="center">
 <!-- Do not remove this copyright notice -->
 $vbphrase[powered_by_vbulletin]
 <!-- Do not remove this copyright notice -->
 </div>

and delete the <br /> tag above it.
