Tech experts please correct me if i'm wrong (but i don't think i am <g>).

Your ISDN connection is *one* side of the equation; the connections (mostly
14.4 - 28.8 modem) of everyone else are the other. If others are
transmitting on more limited bandwidths, it makes no difference how fast
*you* are; the effective perceived transmit speed defaults to the lowest
common denominator.

Also, how is the reflector set up? T1, ISDN, modem? Again, perceived
transmission rate will be a function fo lowest common denominator. Solution
to the problem? Use a fast reflector and only select senders with ISDN or
better transmission rates; not very egalitarian but certainly effective! <g>
