I just pushed a few updates:
- There's a new user preference, Post Preference, where you can specify your default post/reply box (HTML, Markdown, Plain).
- For Markdown and Plain reply boxes, there's a new Show Message History button, that works similarly to how Y! Groups' button works, to insert the quoted message in the reply box. Figuring out replies and how to quote them is not easy, which is why this is currently not enabled for HTML replies, which are much more difficult. It uses a simple algorithm right now, which generally works for plain text and markdown. I will improve it over time.
- Emoji are now enabled for Markdown messages
