Michael, Save us all a headache, and simply register BOSTONU as an alias for BUACCA. In fact, register CCMRG@BUACCA as the contact for it, and CCMRG@BOSTONU as an alternate contact. LISTSERV will recognize both as NAD's for their own systems. Use CCMRG@BOSTONU to delete users from lists, and CCMRG@BUACCA to resubscribe them. Even if you choose not to do that, I'd still set up BOSTONU as an alias. After all, you're liable to be flooded with complaints that non-LISTSERV mail to <fill in the blank>@BOSTONU isn't working anymore. In checking out my first suggestion, I noticed that the routine that decides whether or not you're a NAD (LSVNAD EXEC) doesn't honor the :ALIAS tag. It would be nice if it did, then something like :NODE.BUACCA :ALIAS.BOSTONU :CONTACT.CCMRG@BUACCA would allow "CCMRG@BUACCA" to be a NAD for both BUACCA and BOSTONU. It's a small change, and wouldn't introduce any overhead except when checking for the alias_node, or when the node in question doesn't exist. Eric, is it too late to ask for this one in 1.5o? (I've got it done, if you want it.) Ross Patterson Rutgers University
