Thanks to No Prius Needed (you really are the greatest), I now have a copy of GTR Evolution. If anyone else here has the game and is willing to see if my craptastic internet connection can host races, I've got a game up. Title is "Oppo Challenge", password is "oppo" all lower case.
The cars are GT Club (or the lowest GT level), and the course is Brands Hatch Indy.
edit - Thanks to Vi517 and BlazinAce for coming out. I'm going to try and do this again later in the week, with something more than a "right now" warning.
As it is, I have to drop out due to what's starting to look like a sick kid.
