It's two views of the same list -- everything posted to cctech is automatically seen by cctalk; everything *on topic* posted to cctalk is also seen by cctech. In other language, cctech is a proper subset of cctalk (and cctalk is a superset of cctech). Therefore, if you subscribe to cctalk, you see everything, and your posts go to cctech if they're relevant; if you subscribe to cctech, you only see part of the list traffic, but everything you post is seen by every subscriber. What's worst is posting to both; then *everyone* gets two copies of what you post. -- Pete Peter Turnbull Network Manager University of York
