What if I do not need Markdown formatting for comments in WordPress?

Michel Fortin says: "By default, the Markdown plugin applies to both posts and comments on your WordPress weblog. To deactivate one or the other, edit the MARKDOWNWPPOSTS or MARKDOWNWPCOMMENTS definitions under the "WordPress settings" header at the start of the "markdown.php" file."

What if I do not want the "Extra" features of Markdown Extra?

You can disable the "Extra" features by changing line 62 of markdown.php, replacing MarkdownExtra_Parser with Markdown_Parser. Voilˆ.

For more information on the "Extra" features, check out Michel Fortin's Markdown Extra page.
