Oh, the call for coders thing still applies. Several people have joined already, but more are always welcome. Specifically, we need help with Windows, BeOS, MacOS, and every other OS except Linux. We need people to simply code various parts of the engine. Each package is split into several components.
Coders can sign up to do whichever components they wish.
Descriptions of all packages and their components can be found in the design section of this site. We need people who can test the individual components which other coders write. You need just as much coding experience to test as you do to code, but testing is less work. Testers need to write test programs for components. You can sign up as both a tester and a coder, but not for the same component.
