Since I've got a smart phone plan that covers a ridiculous amount of text messages every month, I've never really wondered how to text for free using an app. But then I tried the free MessageMe app and now I'm completely hooked.
Have you ever forgotten a password? We all have. Now you don't have to worry about that anymore. All you need to remember is one password (hence the name), which will in turn give you access to all of your other passwords. Once you add a password, your browser can log you into your favorite sites using only that one password you made. It's like magic.
