And is there a RESERVEDMODES=yw in CR, and does mIRC understand it? The answer is no. How is mIRC to know it should do nothing with those modes? It doesn't. Why is that mIRC's fault? It isn't. And why didn't I read the CR manual? Because as far as I know there is no freely downloadable version, and there is no way in hell I'm going to pay so that I can read it.
