+==========
+django-tos
+==========
+
+This project gives the admin the ability to reset terms of agreement with the end users. It tracks when TOS are changed and when users agree to the new TOS.
+
+Summary
+=======
+
+    - based flatpage
+    - keep track of when TOS is changed
+    - Users need to be informed and reagree when they relogin (custom login)
+    - 2 models likely (TOS table and user re-agree)
