You likely got an email this morning with the subject "Cmsusers subscription notification". If you haven't already, you will shortly. This is not spam. 

Cascade underwent some routine maintenance last night, but in the process all users were unsubscribed from the mailing list that you receive our updates and web tips through. The email you received was just a notification that you were re-subscribed. 

Please let us know if you have any questions via www.sandiego.edu/web-requests. Thank you!
