Okay, I'm still confused. Is it "iMessage for Androud users" in that it automatically recognizes other MightyText users and sends those messages over the data connection? That point isn't especially clear.

Also, why is there so much emphasis on browser sync? Is the browser install a dependency? Does this work if, say, my browser is closed or my PC is shut down? I would assume that it does, but with the browser sync instructions so heavily emphasized in the install instructions, I'm not sure.
