Well, I went looking for how to password protect a Microsoft Word Document. I don't used that feature too often and I 'Googled' it. I found a clean, simple answer on WikiHow. This is a great resource for how to do a variety of things, step by step and sometimes even with a video.
Matter of fact, they have a wide range of categories from 'Arts' to 'Youth'. Browsing around I found some interesting topics such as How to Communicate With a Deaf Person Through an Interpreter or How to Escape from a Sinking Car. Ok. Some more practical applications might be learning how to drive defensively or how to avoid foods dangerous for your dog. This is a resource worth bookmarking! ☺
