Forum website has no scroll bar.

I am having the same issue, it happens after I search for a topic. I tried in both Firefox and Chrome, something about search returning results destroy's the ability to scroll.

I can tab through the aria features to get down the page eventually, so I know there's content down there.  It's about as painful of as an experience as it sounds.

Please fix your website.  You're comcast.  Come on.

If you are using a computer, it is possible that you might have pulled in the right margin of the screen.

You could try to choose a slightly lower percentage of zoom for the screen (smaller type and pictures).
