added two sample emails for when students have been flagged and for all at the end of semesters

roomlist/housing/templates/email/flagged.txt

+Dear George,
+
+A number of other students who say they live on your same floor aren't sure if you're
+in the right place.
+
+When you get the chance, can you sign in and verify your housing location on
+roomlist.gmu.edu/settings? We want to make sure everyone's privacy is respected.
+
+Thank you,
+
+The Roomlist Team

roomlist/housing/templates/email/year-end.txt

+Dear George,
+
+Well, school year's winding to a close. We hope that you've had a intellectually
+stimulating and personally fulfilling experience over this past spring and fall here
+at Mason.
+
+We're going to clear out everyone's room at the end of the semester, and just
+wanted to give you a heads up.
+
+If you know that you'll be graduating or transferring, you can delete your
+account at roomlist.gmu.edu/accounts/student/gmason/delete.
+
+Thank you, and good luck on your final exams,
+
+The Roomlist Team
