Testing and QA

Are there any plans for triggering an event when the function "message_post_message" is called? We'd like to tie some functionality to when users send messages to one-another, and events give us the perfect method to do so without modifying core Moodle code.

The documentation here:

http://docs.moodle.org/en/Development:Events#Messaging

Mentions a "message_send" event being triggered, but this does not actually occur in the code as of P2 - at least, I did not find one. But, more specifically, I am interested not in *all* internal messages, just the ones the users send to one-another via the user-accessible messaging system.
