When leaving the base, all X-Men are expected to contact the team member on monitor duty and enter their departure time, what they're doing, and when they expect to return. Upon return, all X-Men are expected to log back in with the team member on monitor duty. Failure to record your comings and goings impacts on your personal safety and the safety of your teammates - please use the log book at all times. Cannonball, deputy leader, 25 January 1993.
