I take it you didn’t have a look at [MultiMarkdown](http://
fletcher.freeshell.org/wiki/MultiMarkdown)? It is an extended version
of Markdown and allows for footnotes in general and bibliography
support.
Soryu, I looked at it earlier and thought it was only for BBedit and Moving Type. Your message prompted me to look again and I saw the TextMate Bundle Readme.md. Thank you for response.
I do not think this will thread properly, so I changed my setting from digest to individual emails and will be able to reply then and keep the thread unbroken.
