Using the latest Mac version of Firefox, I just spent the past half hour trying to join your forum but kept getting the message "You did not pass the security check. Please try again." There was no clue what the failure was or how to fix it. I was about to give up when I thought maybe I'd try once more with Safari. This time the Security Check had a Captcha in it. Apparently, the Captcha isn't working in Firefox. I just thought you might want to know about this. I'll attach a screenshot of what I was getting.
As long as this gets to the right people there should be no need to actually post it on your forums.
