With 3 lists, it's not so terrible. If you have lists A, B, C, then you need only 4 super-lists to cover every possible combination: ABC, AB, AC, BC. But what if you decide to add another list to the mix? You would need 11 superlists to cover every combination. Add yet another list and it really gets unwieldy. If you use topics, you only need one list, and you can have up to 23 topics. If you don't like having the topics listed on the Subject: line, there are ways to hide them (the easiest one being to use LISTSERV Maestro to send out your mailings, but there are ways without Maestro) [And speaking of Maestro, the free Maestro offer expires Dec 21, per the latest issue of LISTSERV at Work newsletter]. -- Francoise Becker What are your favorite LISTSERV(R) announcement lists?
