This question about notifications of revisions is marked status-completed
:
Notifications for edits by others of my own questions and answers?
But it's not really completed. The envelope turns red but you don't get the drop-down notification box that says "You've had 3 edits to your questions" or something similar. We get this for answers and comments, but not revisions.
This info is available in the revisions tab, so it's not totally hidden, but the ability to hunt down this information is not the same as notifications.
