How do you unsuscribe from hi5?

First of all, you don't really need to "subscribe" to Facebook, as it is a free service. But if you want to deactivate your account, click on the "Account" tab in the top right corner then click "Account settings" below. The "Deactivate Account" link will appear on the next page at the bottom. If you need anymore help with Facebook, you should check out this online training site called Grovo.
