I see what you're saying.  Conceptually, they seem different but also slightly
similar.  For personal email, if you want to point the user to the first unread
message (similar to a newscan in a sub-board), you could iterate through
personal messages to the user, starting with the first, and look for the first
message that doesn't have the "message read" flag set.  The user could read
their messages out of order, but that would still get them to an unread
personal email.  I think that's what Khelair was going for.
