You can see a list of available public mailing lists. Depending on each list's settings, you may or may not be able to subscribe, view the archives, etc. List owners will also be able to change the settings for their list.
Please do not use important passwords! As email is not considered a secure, encrypted way to communicate, any passwords you use here could potentially be "sniffed". The Mailman server will email you a password when you join a list, and you'll need to use this password to change your settings. Please do not use your login or PennKey password!
To request a new mailing list, send email to cets (at) seas.upenn.edu.
Lists may only provided for SEAS faculty, staff, and students.
