Six tabs along the top of the screen direct you to Home, Messages, Subscribers, Sign Up Forms, Reports, and List Options. Some of these have drop-down options. Links to My Lists, My Apps, and Help, along with My Account, can be found in the upper right-hand corner. Your home page is an account overview which displays new subscribers, scheduled and recently sent messages and list stats.
One of the best feature of Aweber eMail form creator is, you can have extra field apart from Name and eMail. For example, if you need to get the Address or Phone number from your subscribe, you can do that by adding a new field. (The step is easy to do and even with zero design and coding skills you can do that). What I suggest is, simply select any template from the page and you are good to add Aweber sign-up form on your blog.
