The original author is sweede and all credit goes to him. I renamed the addon slightly because as far as I know its primary purpose is for dualspeccing (vs respeccing).
I was searching for a MoP-updated addon that would hide the ridiculous amount of learned/unlearned messages when switching specs, and since I couldn't find one, I tried updating the one I already had.
I'm posting this because I think that other players may find it useful as well. If I am stepping on anyone's toes I will be more than happy to take this down.
*Note - the addon will also silence pet respeccing "learned/unlearned" messages.
