Most times when I go on Multiplayer I File a Flight Plan, which then appears on
http://cockpit.netfrag.org:81/, and indicates that I am/have been using the Service.
Unfortunately, the details only remain on the page for a short time.
You could always upgrade to FSX....

The day that FS Navigator rises from the dead, and gets released for FSX is the day I, and a few others, may fire up my/our copy of FSX...
...and is the reason why you see so many "FS2004+FS Nav" Flyers on the various Multiplayer Sites..

...!
I would also want to see LAGO FSE Scenery Designer released for FSX as well, before I decide to use FSX...

...!
Both of which programs are not going to happen!
So, you can see why so many of us still continue to use FS 2002/FS 2004 for our Multiplayer, etc, flights!..
