This addon is designed to give you a good idea where all those chat and system messages come from. It intercepts ANY message coming to the chatframes you specify, and appends the last known value of "event". This should give you the event that generated that message. Usage is simple:
/mess or /messevent
/mess show all - Turns on event reporting for all chatframes (1-7)
/mess show 3 - Turns on event reporting for ChatFrame3
/mess hide all - Turns off event reporting for all chatframes (1-7)
/mess hide 3 - Turns off event reporting for ChatFrame3
You can your settings by typing /mess report at any time.
