There's really a better way to manage all these e-mail lists than majordomo. Since they're going to be announcement lists, large numbers of people really don't need to be able to post to them. We can just have our own set of programs to use from the UNIX command prompt. We can have one file for the e-mail addresses in each club, and one for the main list, and the uniq program can make sure no address appears in a mailing twice. This will allow us to post to any combination of individual groups, plus the list for all groups, without any problems. I know enough about sendmail and various UNIX utilities to program this, so I'll start right away. I don't think I'll need much beyond the UNIX shell. I plan on using pico for the editor. Here's the idea of how it would work. Let's say there was a debate between the Objectivist Society and Anarchist Student Union. To post the announcement to the proper people, your session wold look something like this: callib@ocf$ announce main objsoc asu Subject: Anarchism versus Objectivism Debate You'd then get in the editor and your message would go out to both groups, plus everyone on the main list. If individual groups want to have e-mail lists for actual discussion, then they can use majordomo as normal.
