If you haven´t seen yet…There are servers online for Q3Rally.
We have one server for Deathmatch, one server for Capture the Flag and one server for Racing. We will update the servers step by step with addon maos and cars and other stuff. As a bonus there is also a server where you can play the actual nightly build. The nightly is available at Sourceforge as always. So you can try out the changes to the game if you cannot wait for the release of a stable version. And now have fun online with friends.
