Staff can access their e-mail many different ways, however the most common way is to simply go to http://mail.brehm.org . This site will work anywhere you have an internet connection.
Currently students have to go to https://mail.google.com/a/students.brehm.org we are in the process of making this more friendly but until then that is where they need to go. Student e-mail is currently only accessible during advisement and free-time.
