I received a LOT of interest in the email I just posted on this Subject, so I hope I find some more !! I was also asked if it could be reposted on another pertinent list . . . of course I agreed. I should have mentioned in my posting that you may share that message with any other list to which you belong if you think it might be of interest or value to those list members (in other words, on-topic).
