I was trying to preview my PM, and discovered a wonderful bug. Open a reply to a private message, edit it, quote a few blocks of it, but don't send. Choose the send later option, to save it in your unsent bucket. Open the message in the unsent bucket. Observe the bug. All the formatting information added by the board has been converted into text inside the message. If you send the message now, it will convert all the formatting html as escaped text, with the html < > and other symbols escaped so they show up as text rather than markup.
