You guys are great...always have been. Meanwhile, I copied the "Published Folder" from my '08 iweb site to 3 different drives (redundancy is my friend). I think something squirrely happened on the upload to my File Manager on Hypermart, because, no matter what I do uploading it, the feed.xml file doesn't show up in the refreshed listing, but I see it in my local files (go figure). So I'll make another iced tea and upload the whole thing again from one of the other drives.
It may just be time to build a new site from scratch though. I'm not sure what functionality challenges are ahead with this style of creation and publishing since I'll still have to use iWeb to make changes, then FTP. Fixing broken links and adding images will probably prove to be a headache. Alas, farewell Apple. I knew you well!
