This ticket is related to #772.
For sites with creation notifications, the comments part of the email is otherwise empty,
and users might want to actually fill it.
I have a working patch relying on the "comment behaviour" system. For the record, this system has been designed precisely to control whether (and how) to display the comments field according to
some transition. In case of a creation, I check "create_content" on the container, and added BBB code so that the default answer is not to display.
So the user has to put, e.g, <comment-behaviour>string:display</comment-behaviour> in the xml description of the create_content transition for the target containers to make it work.
May I check this in ?
