It isn't documented anywhere that I can find, but Benjamin Smedberg's handy Mozilla Status Board tool parses status text as Markdown, which is how I added a Didn't header to the Done section of my status update with all the things I planned to do last week but didn't make happen. (The Done, Next, and Coordination headers are all H4s, so I prepended four hash marks to #### Didn't to make it the same size).
(Note that [Markdown-style links](http://daringfireball.net/projects/markdown/basics) don't work and cause the entire section in which they appear to remain unparsed. However angle-bracketed URLs, as recommended by RFC 3986 <http://labs.apache.org/webarch/uri/rfc/rfc3986.html#delimiting>, work when added to the ends of lines. And "bug ###" references are auto-linkified.)
