Terry wants to know if there's a way he can get a discount on Lynda.com. Leo says he can get a free trial, but isn't sure about a discount on it. Leo recommends checking out iTunes U, since there are a million free courses there, many of them from universities. For casual use, he should start with iTunes U and Kahn Academy. Another option is to look for tutorials on YouTube.
