Well Smithy, let's start with the Zone. Go here: http://zone.msn.com/ ; You will need to install some files, ZONE files for the Zone and Zone Friends. Nothing really big and pretty much leads you through the process. You will have to have a NET Passport if you don't already have one. NO big deal here either. This gets you going on flying on the Zone. If you are running a router or firewall, then you need to look at the MULTIPLAYER section of the Forums. Eno has done some work on setting up routers and firewalls and you should be able to get the info you need there.

For installing scenery, acft., missions etc, Simviation offers lots of help in this area. Look on the main page and you will find under the heading "Help and Tutorials" two great and thorough docs. that will help you tremendously in this area.

Good luck and enjoy flying with others. I sure do.
