The Warn Me Emergency Alert System
This isn't specific to CNR, but it's important nontheless (from http://warnme.berkeley.edu/):
WarnMe is UC Berkeley's alerting and warning service for students, staff, and faculty. It is activated to contact you when there is an immediate threat to safety or health affecting the campus community. WarnMe can alert you by phone, text message, or email — you choose the best ways to reach you.
Be safe out there.
