+Actions are performed by users on items. Actions themselves are items. This requires two relationships: action on item, and user performs action.

+### Flag
+* A Flagger(user) performs a Flag
+* A Flag is performed on a Comment or a username or profile content
+
+
+## Moderation Actions and Status
+
+Comments contain a field `status`. As moderation actions are peformed, the status changes.
+
+* Initial status is empty.
+* When a moderator Approves, the status is set to 'approved'.
+* When a moderator Rejects, the status is set to 'reject'.
+
+### Pre and post moderation
+
+Comments can be set to be premoderated or postmoderated. 
+
+Premoderation means that moderation has to occur _before_ a comment is shown on the site:
+
+* New comments are shown in the moderator queues immediately. 
+* The are not shown to users until (aka in streams) until they are approved by a moderator.
+
+Postmoderation means that comments appear on the site _before_ any moderation action is taken.
+
+* New comments appear in comment streams immediately.
+* New comments do not appear in moderation queues unless they are flagged by other users.
