So far there is nothing really on L4D modding becuase the "Offical" SDK has yet to be released. Therefore, no modding questions, examples, or tutorials are out. Right now, all we can do is generate Ideas and begin mapping for the mod, since mapping is the only thing that can really be done at this point. Otherwise, we'll have to just wait until the L4D "Offical" SDK is released
