The Adobe Community Help pages used to have a commenting system that was specific to the help files.
It is being replaced by a mechanism that creates a thread in the corresponding product forum.
The threads, started by "Community Help", will be titled as and linked to the community help page where the question or comment originated from.
Posts will be mirrored between this forum and Community help.
Comments can be corrections or additions to the help files, and could be links to tutorials posted elsewhere, and should not be treated as spam.
The advantages are the fact that one can post images, videos, or links, use advanced formatting, and the side effect is to draw on the expertise of all the forum posters.
The drawback is that previous comments will disappear, but most have been saved by the Community Help Page Administrators.
