After reviewing support forums, I am afraid to tackle a full-fledged footnote feature in posts with link-back, etc., but there must be a simple way to just format the footnote reference number in a smaller font with a raised baseline to make it look nice. I can do it in TextEdit and save as an RTF file, but the formatting is lost when I copy and paste to the posting at wp-admin. Maybe I shouldn't use copy and paste?
This is my first blog, and I hope to go live in about two weeks. I'm willing to make changes to the code, with instructions on where to do it and where to find the file. I'd rather not use a fixed font size.
