From IM Soft Xtreme:
Xtreme Optin Generator allows your subscribers to receive their rewards instantly without having to go to another page. Increase your optins magically by at least 200% and satisfy your prospects immediately. Personalize your sales letter and address your prospects by name. Boost your response rates by at least 30%. Add images, videos, audios or anything else that can be possibly be placed on a website as a thank you message after they opt in. Works with almost all of the main autoresponder services (such as Aweber, GetResponse and EmailAces).
You can save the generated optin form by saving as Webpage, place code in your clipboard to paste in your HTML editor, save as Wordpress plugin, save as Wordpress sidebar widget, and upload your web page to your web server along with the "sub pages" that include your form's name.
