Gary, thank you for the very comprehensive overview of the system. With your permission I am going to incorporate it into the main body of the web site next week so that when this comes up, ( which we all know it routinely does) we can link right to the spot where all the explanation is. Nice job. If you want to add anytthing to it, jsut send it to me as as word doc or email and we'll have it all covered for the future. We do keep the guildlines ( as curent as they have been published) on the site, and this should be added to that section.
