I think there must come a now forum on splashdamage.com called “level editing for Quake Wars”. Because the forum “level editing for enemy territory” is one of the biggest forum for enemy territory mappers. And now there is Quake Wars. And the SDK is out. So why not?
I sure know that there are a lot of people waiting for this forum
