Learn to Use Photoshop and Other Applications at TechTutor.TV

Each video teaches you how to perform a specific task, such as creating custom lists in Excel or creating a layer mask in Photoshop. Thus, these tutorials are best suited to users who have at least a little experience with a given app and want to improve their skills. You can search the available videos or browse by application. You can also embed the videos in your own site.

These are great little learning tools for folks who prefer video instruction to printed manuals or reference guides. (They're also a smart use of Revver, the YouTube-like video hosting service that generates revenue each time someone views your video.)
