I have started by selecting the most suitable site for my needs. I will learn Chinese with Yangyang. My boy brought the link home from school. 10 free lessons are up on the web that suit my learning style, progress fast enough. Yangyang is great, funny, to the point and easy to understand. A list of other useful Chinese sites is up on the project Wiki.
Can't wait and have decided to make time of at least 15min a day for the learning of Mandarin, my new language!
