This one is just a good idea! Check out Teach Parents Tech at http://www.teachparentstech.org/. actually built this site to help kids help their parents learn technology. The super easy interface and great make it even better. Kids can send parents tutorials on categories such as The Basics, , Communication, Media, and Finding Information.
I checked out the information and it's awesome! You fill out a template letter and it packages the tutorial with the letter and send it. Love the media section..it has good stuff for anybody!
This is a must see! Give it a look!
