It is also possible to have MF email you an entire thread (original post plus all replies). The tree structure will be lost; you will receive a single email with all posts in the thread.

Next to the reply button on any post in the thread is an "email post" button. If you click it, then enter your email address and select "the entire thread" button, you can save your favorite threads.

The email may take 5 or 10 minutes to arrive.
