I would like to start a thread for sharing great websites with additional resources or tutorials. If you post to this thread, tell us what the site is, who it is for (audience), and who the training is targeted for (adults, children, seniors, etc.).
Here are two great sites for trainers.
Digital Literacy Teaching Tools = From the US government, you will find links to tools/ tutorials on a wide variety of topics. http://www.digitalliteracy.gov/content/educator. This site is for all educators who teach all levels.
Quick Picture-Based Tutorials= This site is free and focuses on the visual learner. Limited text and mostly images, it contains tutorials for Office 2003- 2013. http://inpics.net/. This site is geared more towards adults who want to learn how to complete a task.
