I've tried to send feedback several times directly from help.adobe.com but this is what I always get:
"Sorry, there was an error in posting your comment. Please try again later."
This happened on ADC too. Very frustrating for someone who wrote a lenghty comment already...
This may not be the best place to report it but I hope you can forward this to someone who can look at it.
