What does the "MP" (as an alternative to "PM") actually stand for? Sorry if this was already asked.

Also, as an idea, if not already mentioned, perhaps you could make a message appear whenever you get a PM in the chatbox. For example, if you're viewing a different channel, a message could show up, much like if someone had posted something, that says something along the lines of "[date/time] ________ sent you a message. Check your PM channel to view it". I'm only suggesting this because you can't really notice if someone sends you a message unless you're checking the channel every-so-often.
