I'll fix it if you promise to never again auto-quote the entire digest. ;)
Just kidding--I don't know how to fix it, and I think the programmer of this listserv's code died in the 1800s, so you might just have to deal. Sorry--some of us have tried for a while to move the group to something like a forum, to no avail.
Maybe you could switch to just viewing the archive, although that means you'd have to remember to check it regularly (I used to read that way).
