As an undergrad, my email was hosted on a VAX. And, some of us wrote little scripts and programs on them. We particularly had fun with mail bombers, which were scripts that sent the same message over, and over, and over.
We won't do that. But we can write a simple program for sending a note to all of our classmates.
The Python Tutorial will likely come in handy on this project.
(This isn't a lab so much as a mixed in/out-of-class assignment-exploration-thing.)
