What do you need? Everyone needs TNOS100E.ZIP and TNOS100D.ZIP, these are docs and assorted support programs. There are initially two different executables that you need only one of, TNOS100A.EXE and TNOS100B.EXE. These differ only in that "A.EXE" has: POP3 Server and Client support SAM Callbook support AXIP Enhanced Conference Bridge HOPCHECK and "B.EXE" has: POP3 Client support The "A.EXE" is a loaded version, primarily for a server, while the "B.EXE" is more of a user version. The other features are the same between these two versions. I MAY supply other executables with different feature sets in the future. Then you need the proper HELP zip file, either HELP100A.ZIP or HELP100B.ZIP depending on which executable you chose. Use "A.ZIP" with "A.EXE", and "B.ZIP" with "B.EXE". Source Code? If you want the source code, get TNOS100S.ZIP, also. You'll have questions...... When you do, consult the file "readme.doc" in TNOS100D.ZIP for the most effective way to get my ear.
