+# Report
+
+Allows players to report things to admins and online moderators.
+
+Suppose `player`, `griefer` and `moderator` are online players.  
+`player` runs this command: `/report griefer is griefing`  
+`moderator` sees: `-!- player reported: griefer is griefing`  
+The Admin (named in "name") is mailed via chatplus: `<player1> Report: player2 is griefing (mods online: player3)`
+
+License: WTFPL  
+Depends: chatplus.
