Given the little taste of SPAM on the Advocats list recently, I'm
trying an experiment. Any posting from a nonsubscriber will go to
the list owner for approval; all postings from subscribers will go
directly to the list.
New subscriptions outside uvm.edu have not been allowed for a long
time, but it has been possible for anyone to send messages. The
change I've made means that:
 You'll have to post from an address under which you're subscribed.
 If you need to post from multiple uvm.edu addresses, subscribe
from all those addresses, and set all but one to "nomail".
Please let me know if this poses a hardship, or if it doesn't work as intended.
