Lynda at the Library
Lynda.com is a great teaching site for learning computer software. The teachers are top-notch.
It's inexpensive: $20/month: www.Lynda.com
You may be able to get access for free through your local public library.
This is how my daughter is learning Adobe Premiere Pro, the video editing program. She logs in to the library's site, and then goes to Lynda.com.
This is the best way to learn a new program.
