I'm replying both to Eric as well as the list, in hope that this idea sparks further suggestions... In terms of developing a user-friendly client in the Macintosh world, I would think that a Hypercard-based application would be the best way to go. Given that all Macs are shipped with at least a fully functional Hypercard player (i.e., runtime module), such an application would be usable by the majority of Mac-equipped Listserv users. As an example of a nicely executed hands-on Hypercard tutorial, I suggest you ftp anonymously to nnsc.nsf.net and retrieve the file Internet-Tour4.0.2.sit.hqx, located in the root directory. You need at least Stuffit 3 to uncompress it, but that's found on sumex-aim.stanford.edu, in the /info-mac/util directory. (As a side note, you might also want to take a look at this Hypercard stack, for use as an introduction to the Internet by your new users). Hope this helps. Juan Courcoul
