This doesn't solve your immediate problem, but we get around it by requiring everyone who subscribes to send a profile and a reason for wanting to subscribe. Without that profile -- which comes directly from their account to a listowner's personal account -- they are not subscribed. Actually, requiring the profile has (so far) served to keep the spammers out, as they don't want to go to that much trouble. Michael S.
