Sometimes, when I go to the advertising forum, I get a completely white page. I've tried going to the subforums (which do load fine) and then clicking Advertising as well, no dice. This has been happening for at least a month now, maybe a couple times a week. Not sure what triggers it. I'm using Google Chrome and Windows.

This happens to me, too! It's been happening since I joined in January, several times a week. It always eventually loads if I refresh it several times, though, so I'm not totally unable to access the advertising forum. :) I'm on Firefox & Ubuntu.
