This solves the social problem of invading someone's inbox with bulk e-mail, but it doesn't solve the loading problem. In an emergency we want everyone to read the e-mail. I fear that we otherwise will come up with a whole web of special electronic policies. Majordomo is used for e-mail lists. Deans and departments have a legitimate reason for bulk e-mail.
Departments automatically have a facility to access their own students.
There are two uses for Bulk e-mail. The e-mail could recycle the mailings list, handle the process of using the mailing list. Matt has a good way to look at this. We need to define categories. Let's form a sub-committee to look at this issue.
