I'm new to wordpress. I have to create a one page template for my site and show a subscribe textbox on it with my own custom style. Later, I will use it to send monthly newsletters. What can be the simplest way to do that? I saw into some plugins like newsletter, subscribe2, but they are complicated and I don't know how to integrate them with my text box. They just provide some sort of widget to show on sidebar. Any tutorial or simple plugin? Please help!
