Thanks Mr Reed.
Sorry it's been so long my finding this posting.
Since I wrote the original question, "Piedmont Virtual Airlines" has changed to a new site and the people who used to run it are gone, at least their version of the site is.
Here is their site now...
I am in no way involved with that site, but I do appreciate that they are there for those who want to join it.
It's a nice little virtual airline.
I had provided the other guys the TRI schedule to the best of my memory.
That was quite some time ago.
Anyone who has an interest in flying flightsim software and wants to fly Piedmont aircraft doing it, this is a great little site on the net.
