Online Tools and Programs for Collaboration: Research Project

I know this is a little late, but I completely forgot about it!!

My research project was about online tools and programs for collaboration. It was a completely foreign subject to me when I picked it, so throughout the entire process it was a learning experience. The gist of it is, is the ability for two or more people to work on the same project while being in different geographical locations. There are many types of tools and programs for collaboration available, and you must purchase them before being able to use them. Although I was not able to find out much about the entire process in my short period of time, I learned much about the topic considering I knew nothing. Seems it can be used for many different things, school, work, fun, entertainment, or whatever! Very interesting and glad I picked a topic so foreign to me.
