I've created a tutorial to help with using the site. It is longer than I hoped (3 pages), but there is a lot of new stuff. Unfortunately, I've left a few things out. The best bet is to just play around and see what you can do. I hope to have the video tutorial up soon.

The most important piece of advice: "Open rich editor" in the body of your message to create formatted text, rather than one long paragraph. It is the only way to put line breaks in your messages.
