Search the list's archives for the answers. Unfortunately the archive's search facility is effectively hidden in that it's only presented on the web page that describes the list (which most people only visit once), as opposed to the archive pages themselves or the page that the link included with each message to the list takes you to -- which would make a lot more sense.
