You can but only once per post,
but its one way traffic they can not reply,
so its easier in the long run to either quote the post
of concern, copy it and post it in your private moderators forum.
This can then be discussed.
Your also assuming that your moderators "Always" read there e-mail.
They dont or when they do days have gone by.
If you really want to do it your way and use the notify
to communicate with moderators then just click notify
on each post until you can post a comment.
Hope that helps ?
