Other places where Markdown Here works

Besides Thunderbird, Gmail, Hotmail, and Yahoo, Markdown Here has been found to work in...

Google Groups

Markdown Here works with Google Groups posts. You can use it in the GG rich compose box, or when you're posting via email. One caveat: Digest emails strip all styling.

Evernote

A user discovered that Markdown Here works in the Evernote web interface.

Caveat: It seems that newlines are stripped out of code blocks, so they display as a single line.

Postbox

Postbox is a non-free desktop email client based on Thunderbird, and user markgoodson requested that Markdown Here support it. The Mozilla extension now works with it, but with some major caveats:

• There's no options page. However, you can open the "Config Editor" from the Preferences dialog and copy/paste options from Firefox's or Thunderbird's equivalent config editor (about:config in Firefox, "Config Editor" in Thunderbird). Note: Make them all string values.
• Line breaks can appear mysteriously in code blocks. Postbox seems to insert unescaped newlines into the raw email when sending, which cause problems if they appear in the middle of a <pre> block.
• Gmail and Thunderbird reply exclusion doesn't work in Postbox. It doesn't seem to put the original email in a <blockquote>. You will have to use Markdown Here's selection conversion, like with Yahoo and Hotmail.
• Postbox won't be a first-class client for Markdown Here, partly because my trial license for it expires soon. If something breaks, create an issue.
