I went to their online chat on their website. Very helpful answer questions.
My question: Downloaded aweber plugin no problem, but when I drag it to the side bar I get this message: AWeber Web Form requires authentication. You will need you to update your settings in order to continue to use AWeber Web Form. So I click on settings link, it takes me to another link, 'click here to get authorization code. I click and then it goes to aweber site asking for a user name and password.... Where do I have to go to get a user name and password? Using WP ver 3.2
Reply: You can order an AWeber account right here: https://www.aweber.com/order.htm
Use our service to make the web form. It is in one of the final steps of the set-up wizard, and then you can use the plugin to place the form you want to appear on your sidebar.
