Scroll bars, scroll bars, scroll bars. Ben, you have three scroll bars on this page. Two are vertical and one is horizontal. This is a big problem with using frames. You must insure all elements fit so that scroll bars are disallowed in all screen sizes.
People expect a scroll down the far right, but they dislike that vertical scroll on the left frame.
They HATE the horizontal scroll. You'll lose the horizontal scroll simply by getting off the free server. That scroll is being produced by the banner ad at the top. I'd say to lose it, but I'll bet you can't. If you're going to use frames, you must, must, must, do whatever you can to lose any horizontal and vertical scroll, except maybe the scroll on the far right of the browser screen.
