The rich text editor is not compatible with your browser. You may see some HTML source displayed. Any BBCode you enter will be converted to HTML when you save.
Obviously the new Firefox 7.0 upgrade is not compatible. I am seeing BBcode.
I'll check what the Huddler folks are up to on this, and report back. Meanwhile, on Firefox, check your Tool/ Options/Advanced/Updates/ and de-select automatic updates and select "Ask me what I want to do". Firefox has been adding updates at a record pace, and IMO they are not very often ready for prime-time. If Firefox needs 3-updates every month to fix "vulnerabilities" or security issues, it might be time for me to use a different browser.
