In the Email Notification of a new message in a Post that you are interested in, could there be a 'View this Message' Link, either instead of, or as well as, the 'View this Thread' Link.
The view this thread link just goes to the start of the appropriate page, so has to be scrolled down.
If you enable say, 20 messages per page, this can be a nuisance.
As the email is in reference to a specific message, I feel you should be directed straight there.
