I still have problems with the quote feature. I click the quote icon on the post and a small window pops up saying, "Retrieving Quote" and nothing happens.
A window, or a banner at the top of the page? I'm not able to duplicate this problem as I don't have any computers with IE8 on them, but my advice would be to use something other than Internet Explorer 8, if you can. If not, I'd collapse the quick reply box so that the quote button uses the standard reply form instead.
