Communication

What I know were you can communicate is sanding messages on the internet,or with a little camera and you can see to each others,or getting in web said like on moco space,myspace,IMVU,or facebook, or messenger,and some other stuff were you can communicate. Why I think is important is because you can communicate to each other.Like when I'm in Mexico and my mom is in Texas I can communicate fast but if she is not online I cant  communicate with her.But I steel  can communicate in the phone but that is with out internet.But the one that I like the most is communicating on the internet.
