How would the DONs in this group feel about having their own discussion group at http://www.egroups.com?
It is very easy to start a mailing list there. I currently own and moderate a list called EldercareSupport. It is a small group so far, but I think that it is very worthwhile. Just thought I'd suggest egroups as an option for you. I know how tough your job can be and it is nice to be able to vent about different topics to others that understand.
