It may be possible for Addressing Services to distribute e-mail to other lists. For example, you can request to send to all faculty in the Biology department or to all staff in Chemistry and Microbiology. Yes, the paper distribution system has not changed. You can choose to distribute information via print in the usual way or you may choose to distribute information via electronic mail. For the latter you now have more flexibility.
All documents sent to the campus lists go through a moderator.
Documents not appropriate to the University will be returned to the originator. You are likely to get some e-mail not of interest to you just as you currently get some paper mail not of interest to you.
