I would like to introduce you my subsite dedicated to self-learning. For better understanding and that you will never get to an issue and say “How it was done?” you can get free video tutorials.
 
All tutorials were made with screen capturing program called Wink (http://www.debugmode.com/wink/).
You can use tutorials however you want. 🙂
