My opinion is that separate lists are not needed (and I'm not clear on how the person with the original idea summarized opinions in a way that led to the conclusion that a new list is needed), but that a different medium may be needed. The problem with e-mail is that to many users, especially those who don't search the archives, e-mail is "memoryless", and that individual e-mail messages become cumulative rather than being corrected or updated. How many times have we seen almost identical questions posed only days apart? A well-organized discussion board (e.g. http://www.knoppix.net/forum) or wiki (e.g. using methods provided by twiki.org - see http://web.brandeis.edu/pages/view/ITS for a nice example; other users will know of better examples) is worth considering. It would be especially nice if before pressing the "Submit New Message" button a user had to check a few boxes acknowledging that she had consulted various sources of information, and besides the checkboxes would be links to those sources. Topics and subtopics would have to be created by an administrator but users could add sub sub topics and, optimally, edit other users' responses. This approach would IMHO get better participation by both novices and experts than would having two lists.
