            G-mail and posterous 

posterous is a good way of communicating because it is free and you can access to it at any time and any place if you have wi-fi though . it is good because you don't have to pay to use it . if you use it at school and you didn't get to finish something you can always go home and finish it off when you have a free time .

g mail is a  good way of communicating because it also free and easy in use . if you have a g-mail account you can access to things like blog spot which is similar to posterous but its better you can also access a calendar which can send you an email reminder of upcoming event .Also it has a thing called " drive" which  has a power point , word etc so you can use it on any computer  without having to carry your pen drive with you .
