Nice idea! Do you mind adding one more site to that list?
"IL2 Air Racing"
Links: IL2 Air Racing Forum IL2 Air Racing Official Website
Air Racing has been with the community since the first IL2 and is the only organization willing to host a racing server today. You can find the server in Hyperlobby (Air__Racing). It features "Reno" style pylon racing and sometimes cross country navigation races.
Air Racing is a lot of fun and all are welcome to join the league. It is a great way to escape the fighting for awhile, show off racing skins, and be the fastest pilot in IL2.

Good luck! And remember, no shooting.
