This plug-in allows you to write posts (of any post type) using the Markdown syntax. The plug-in converts the Markdown into HTML prior to saving the post. When editing a post, the plug-in converts it back into Markdown syntax. The plug-in also allows you to enable Markdown in comments and BBPress forums. In these instances the plug-in adds a toolbar, and preview of the processed Markdown with Prettify syntax highlighter applied (similiar to that used in the Stack Exchange websites such as WordPress Stack Exchange). WP-Markdown stores the processed HTML, so deactivating the plug-in will not affect your posts, comments or bbPress forums.
