Guys, I am going on vacation for a week or so and I have been trying to "unsubsribe" for the passed couple of days (because I receive on the average 50-75 e-mails a day). The agency takes a very dim view of this. The address I have been using is : Majordomo@coimbra.ans.net, with the statement: unsubsribe quattro ACA@NRC.GOV. Is all this correct?
