        Yeah, I'm beginning to discover how many of my members are
subscribed under aliases which allow them to receive but not to send.  Don't
those messages come back to you as a BOUNCE, though?  If so, you can notify
the member of the deal and tell them to subscribe under their real address.

        Fortunately, the first person this happened to is very e-mail
literate and figured it out ... he spread the word for me before I could
even discover the bounces.  [laugh]  Ain't list maintaining fun?

        Larry.
