Google Docs is the best way to do your assignments for class. You can start on the assignment at school and finish it at home. I use google docs a lot.
I think it is a great tool of technology.
This site helps you design your own hang out. You can talk to a circle of friends. You may talk face to face with your friends over the internet.
I have used Skype many of times. You can talk and see someone from around the world. This is how my current husband and I communicate when he is working offshore half way around the world. My son gets to see and talk to his dad. It helps a lot. I think that it is great to see someone who is that important to your family.
