Actually it is, but that link doesn't seem to working direct anymore.
I have it stored in my favourites and it works fine.
If you use this one;
http://zone.msn.com/en/flightsim98/article/fsimnicknamerequired?StopLoginReturnC... to first log in, then the other to get to the Flight Sim page, it will work but you won't be able to see the flight sim's yet.
Wait a few seconds for the page to open and your Zone Friends menu to come up, then press "Refresh" in your browser. The page will refresh with the full games menu for that area.
"RidgeRunners" has now been removed and replaced by "Furball", which has more players allowed in a game.
The number of players already in there changes according to the day, and time of day.
Look forward to seeing you in there.
