Suggestion: If I drop a quest, Carbonite could print in the chat window "You dropped: <hoggers new adventures>" much like you print when we complete something (just for me, not the party)
That one is kind of ugly, because of the message box. The box is the standard Blizzard one and it abandons the quest, so we don't really know if you hit cancel or not. When you click abandon the quest log updates and we rescan all the quests and do see something is missing, but not why.
