Advantages: Fun! Easy! Free! Educational Great online asset for both students and teachers

Weaknesses: Not for kids at all Can be open to people your business competitors (anyone that you don't want on there can get on; it is possible if you don't set up your secuity right) Makes the browser slow

I give this site an 8/10 due to the live collaboration and how you can stay with your buisness online, but how //slow// it makes your browser after the fact.
