For some reason, Kevin, when I send text to the PIClist, and that text is read by a copy of Eudora, the reply from Eudora email users comes back with this garbled code instead of brackets. I have pulled out all my hair trying to fix it, and have given up. Since I don't have Eudora around, I can't really set up a test. There is some magical Outlook express MIME/text setting that is set on my computer, and my efforts to change it have not resulted in anything but trouble and the more I mess around with them the worse it gets. My apologies, try to ignore it.
