Drop Box

We recently created a presentation and needed to share it with the class. I had no idea about Drop Box, until it was presented to me in this class. It is very simple to use once downloaded. I can't believe that I was able to literally drag and drop my file into the box icon and it would then be saved online and create a URL. The URL makes it very user friendly to share with others, without emailing yet another attachment. I can see how this program would be useful for large files or presentations that can be accessed from any computer problem free.
