From time to time we'll use it for assignments and shared publication, much in the fashion of a class bulletin board!
To publish a post you just have to send an email to XXXXXXXXX, and it will be published automatically. Keep two things in mind, though:
1) You may want to include your name at the bottom of your post.
2) Send images as attachements to have them published. That would be very nice! You can also link to them in the body of your email. (The insert image option in gmail also works fine).
