This just works!! And works well!
Note on this plugin that you do not need to put in the footnote numbers. It will do that automatically for you. I love that because if I insert text or move things around in my writing/editing process this plugin takes care of resetting the footnote numbers for me. HUGE savings of time how I was doing it before - manually.
I did try out a few other Footnote plugins today but found this one to be the best.
Note that the manual for use is here: http://elvery.net/drzax/wordpress-footnotes-plugin. It has some good tips and some important info to make it work right (e.g. always having a space before the (( and other quick tips.)
Very well designed plugin. Thank you!
