Gmail

This means that students can only exchange emails to another student or teacher within RBUSD.  Elementary students can only send and receive email to elementary students and the same goes for middle school and high school students (they can only send/receive to middle/high school students according to what level they are).  Outside RBUSD email addresses CANNOT email students.
