G'day.
It is apparent that, since the upgrade to the website with the somewhat new-look forums, Firefox users are no longer welcome to post replies or new topics.
Fortunately, I have Internet Explorer as well as Firefox (though I prefer Firefox), and so I am able to post this comment.
When seeking to post a reply using Firefox, I get the message "You cannot reply in this forum". When attempting to post a new topic, I get the message "You cannot post in this forum". When I tried to post a new topic in this Technical Support forum, I got the message "The submitted form was invalid. Try submitting again." Needless to say, trying to submit again seems to only lead to a poistive result when using Internet Explorer.
I use Mozilla Firefox 3.05, Internet Explorer 7.0.6001.18000
