All, I've got a list (LISTD) with LISTA, LISTB and LISTC as sub-lists of it. The super-list is to eliminate duplicates: people subscribed to more than one of the sub-lists should get only one copy of general announcements applicable to all lists. QUESTION: Is there a way to get a list of all subscribers who would get messages sent to the super-list that I'm missing? I've read the manual and searched the archives about super-lists with no leads. I would use such a command to fix subscriptions from [log in to unmask] in one sub-list and [log in to unmask] in another. (My subscribers are from a population where I can be sure that these are definitely the same person.) As it is, I query each sub-list, sort, compare, then cull. Complications arise when one list has the two subscriptions with one set to NOMAIL and another list has the same subscriptions with the other set to NOMAIL. In other words: LISTA: MAIL - [log in to unmask] NOMAIL - [log in to unmask] LISTC: NOMAIL - [log in to unmask] MAIL - [log in to unmask] So LISTD would end up sending duplications to 'person', one to each subscription. I fear the feature I'd hoped for wasn't designed into super-lists. Issuing 'query LISTD for *@*' gave me only the person directly subscribed to LISTD (me), not all the potential recipients. Might there be a SUPERSCAN command that would return SCAN-like results on a super-list? SUPERQUERY that does QUERYs on super-lists? SUPERdreaming, En paz, Steve -- Stephen W.

Cuz it could be.
