Fully tested and compliant with Firmware 4.1.8. There is a chapter of the book specifically about running a mailing list on the Mac and a section specifically about Macjordomo. Again, slightly out of date, but the basics are there and very nicely presented, with screen shots etc.
Retrospect works fine.
But this is not a problem. If a new version has problems they are usually caught within a few days and the version is withdrawn from the site or a newer one is posted. If the alpha version is at least a month or so old and there are no newer versions on the ftp site, it's probably the best choice to use. Can I use AppleScript with Macjordomo. Start your script editor, choose Open Dictionary from the the File menu, and open your copy of Macjordomo to see what you can do.
