Alan Check out the archives for this list on the web. The address is: www.mallorn.com/lists/prairie/ There was quite a bit of discussion about this subject at one time (February?). The archives are organized with subject headings but all the subject headings don't neccesarily reflect what is in the message, so check them all to be sure you're not missing anything.
