This is so easy even a newbie can do it-
If you open your text module in edit mode, click the html button and put: <hr /> where you want the line to appear it will...
I'll add it in here to show you (yes you can do it anywhere on the site with access to the html box) the line below is it (simple, grey, yet powerful divider): (below the arrow) it puts it across the page but I've found by accident that placement could create some cool line effects...
you can also do double lines just by using the tag more times i.e.:
<hr /><hr />
I wish they'd put one of these between the main title and subtitle (hint hint Simon)...
tonoffunguy you should add this ditty to your page on html...
