Custom CSS

I'm trying to wrap my text around a portion of the webpage that I've designated
as a column. Before you look at the page I'm talking about, my intention is
that the MAIN text wraps around the sidebar on the right-side of the page when
all sidebar content is finished.

As it is now, there is a long white empty space when sidebar content is done.
Please take a look and gimme feedback. Thanks,
<a target=_blank class=ftalternatingbarlinklarge
