Those of you I set on digest mode, note that I chose a MIME format for the digests for you. That seemed better than plain text (haven't we had enough of that?), but you might want to try that format if you don't like the MIME.
I have configured the list to send out a reminder once every two months. I don't yet know what the text of that reminder will be. We're all on this ride together...
