Hi, I am switching a mailing list that I have been maintaining using local software over to a listserv. My question regards how to do the initial switch-over. I'd like to sign everyone on my mailing list up for the listserv. My problem is that I only have email addresses, not real names. I'd like to just sign everyone up using the "real" name "Gymn Subscriber" or similar and encourage them to change it themselves. But my understanding is that if I do this this name will overwrite their real name for any other mailing lists they may be subscribed to on the same listserv. I know that I don't need to use a real name if they already subscribe to a list on that listserv, but I'm sure some of my subscribers are already on a list and others aren't, and I don't know which group any individual belongs to. So... what I'd like to do is somehow specify that the name I'm providing should only be used if there *isn't* already a name on file for that person. Is there a way to do this? Any other suggestions for my situation? Thanks a lot, --Robyn
