Roger, The client will come in two versions, a mail-only version for PC users without TCP/IP (there are MANY of these), and a TCP/IP version. I can't speak for Logika and can't say whether it will be in the first release, but support for MSP is definitely planned. This would allow the client to send commands to LISTSERV and display the reply interactively, assuming of course that the target LISTSERV's host supports MSP. But, as you know, mail is the only thing guaranteed to work everywhere. Eric
