The real problem was changing my userid to that on another system. The local administration decreed that all electronic mail not directly related to Social Studies Computing is an abuse of the system. Thus I needed to change my entry on the list from this account to that of another system. I'm sure the UNSUB command would have done half of that, but I would not have been able to instantly add the other account to the (closed) list, and thus I would not have seen any of the mail during the interim. Let me expand on your question of security to be able to make a correction of this type... changing the name would not seem to cause too much problems, but would being able to correct ANY field (such as userid/node) via some sort of CORRECT or UPDATE command -- is this giving too much power? If the argument is made that this would allow the user to add someone to the list, the counterpoint is that that user could have just as easily forwarded the mail his/herself.
