Comment 5 for bug 673203

After talking with Graham on IRC, we have some cleanup to do around the change that led to this bug.

We need to:

 * Be sure if we're sending email notifications to subscribers via duplicates or not
 * Make sure the web UI reflects this state accurately (i.e. don't display the user if he/she isn't getting mail)
 * Make sure we have a direct link to the master bug first
 * Then a notice if the user is not subscribed and a link pointing to where he/she can subscribe
