PHP Markdown
The Markdown plugin as delivered in WordPress 1.2 has some flaws. For example, you can’t add the “optional title” attribute to a link as John Gruber implemented it in the original plugin for MT:
[John Gruber]: http://daringfireball.net "John Gruber's Daring Fireball"
Now I downloaded the latest version of PHP Markdown from Michael Fortin’s page. This version supports the “optional title tag”. Neat!
I’ll have to checkout the PHP Markdown Dingus again to play with the markdown.
