I wish there was more medium level content like this available for office. It's easy to find basic tutorials of the 'Press the B button for bold' level. You know, where messing around with the interface for a few minutes brings you up to speed. Also easy to google for VB stuff and manual-style things. What function or code sample do you need to accomplish X. But the level in between, where you find about less known functions and interesting usage of tools, is hard to learn. You can stumble around until you find a gem, but I am not aware of organized repositories.
