Skype

Skype.com is an online collaboration tool. It is free to download but requires a small microphone and optional webcam. Skype allows people to communicate worldwide (28 countries). It is useful for travel, business, and even education. There are many features including a visual phone call and the ability to talk with multiple people. Students and teachers have used Skype in editing papers and projects, where one would need to explain the corrections. Skype acts similar to a phone call, in that it allows people to contact others whether they pick up or not. You can send messages or forward the call to their office or cell phone. It is easy to use and easily accessible.
