Can I try that out with a LISTSERV-LITE Installation. Or, where can I find a test 14.4 server? And, maybe somebody here can elaborate shortly on the version-history of LISTSERV (as I wrote already I'm relatively unexperienced with LISTSERV). RELEASE on our site yields: LISTSERV(R) for Windows version 1.8e, managed by: [log in to unmask] [log in to unmask] Master nodes file version: 2001-02-07 08:30:26 (VERS9922) NJE peers file version: 2002-04-03 17:09:14 Internet peers file version: 2002-03-26 17:49:58 Service file version: 2002-02-26 10:39:10 (VERS9922) Alias file version: 2002-05-03 13:15:50 Running under: Windows 2000 Advanced Server SHOW LICENSE gives: License type: Permanent Expiration date: None - perpetual license Maintenance until: No maintenance information Capacity: Unlimited Version: 1.8e Serial number: IZ-SOZ-4 Build date: 27 May 2002 As far as I understand 1.8e is the same like either 14.0, 14.1, 14.2 or 14.4. A bit confusing for me. I have not done the installation. How can I tell which one I have, can I upgrade to 14.4 with the present license and what do I need to have in mind concerning the license keys? Thanks a lot, Oliver
