We can start talking about Google docs which can be used for IT projects with students and colleagues.
Let's watch a Plain English video to understand the concept of this fantastic tool.
Personally, I do not save my files in the hard disk any more. I use Google Docs because I have access to all my files from any computer with Internet conection.
Sharing files is very useful and important. I hardly take xerox copies or print documents. I just share my files with the people I am working with. Google Docs not only reduces our shelves burden with piles of sheets of paper but also contributes to protect the environment.
