aweber sign-up box

I have a signup box on my website [login to view URL] Please view this. The signup box was created using email subscriber plugin for wordpress. I want to use aweber, not email subscriber plugin for wordpress. I want the same visual design as what is on my site now, but I want it setup via aweber. The sign up box appears on the homepage, 5 seconds after the users loads the page, it appears on the sidebar of the blog (i also want to keep the same design here except just want to centre the text of the message when it appears) also it appears when the user clicks subscribe on the bottom of the page. Once the user has subscribed the box should not appear again for that user. Please test this signup box so that you understand how it works and what messages are displayed as I want to keep the same messages, including what messages are shown when the uses clicks sign up, and if the user enters an email address that is already subscribed. please only respond if you have experience with aweber thank you
