Left sidebare

You'll need to change the width value in page.tpl.php, the lines to change are:

<?php if ($right);else echo "<style type=\"text/css\" media=\"all\">#main {width:660px;}  #main .inner {padding-right:0px;} #mission {margin-right:0;}</style>"; ?>
<?php if ($left);else echo "<style type=\"text/css\" media=\"all\">#main {width:660px;} #main .inner {padding-left:0px;} #mission {margin-left:0;}</style>"; ?>
<?php if ($right);elseif($left);else echo "<style type=\"text/css\" media=\"all\">#main {width:448px;} #main .inner {padding:0px;} #mission {margin:0;}</style>"; ?>

Open up style.css and change:

#main {width:780px;}
#sidebar-left {width:120px}

The way it works just now is a bit ugly. I'll really need to update it using template.php instead to split out css classes in the body tag for left and right sidebars, though it will do for now until i have some free time.

No worries, also you may have to clear your cache after making changes.
