VERY interesting point. I was definately thinking of "No Mail" rather than
"No New Mail". I'd not considered the possibility of using POP3 services
without deleting read messages from the server. Leaving a copy on the server
will absolutely run the resources use through the roof if enough folks do
it. No sure how/if/why to limit frequent checks to "Download All Everytime"
users except through Education (not an option in some cases<g>).

Well, if you expect 5-minute turn-around, and GET 5-minute turn-around
usually, a lot can be accomplished. If you DEPEND on 5-minute turn-around,
you are asking for trouble and need to move toward instant messaging or the
phone (or morse code, if that's the way you like it - I sure do).

Thanks for the clarification.
