Everyone should add themselves to the cse341 mailing list. To do this, visit the CSE 341 mailing list website: http://mailman.cs.washington.edu/mailman/listinfo/cse341
You can even customize these web pages from the list configuration page. However, you do need to know HTML to be able to do this.
There is also an email-based interface for users (not administrators) of your list; you can get info about using it by sending a message with just the word `help' as subject or in the body, to:
cse341-request@cs.washington.edu
To unsubscribe a user: from the mailing list 'listinfo' web page, click on or enter the user's email address as if you were that user. Where that user would put in their password to unsubscribe, put in your admin password. You can also use your password to change member's options, including digestification, delivery disabling, etc.
Please address questions about the mailing list administration to to mailman-admin@cs.washington.edu.
