If you want to incorporate the similar lightbox newsletter sign-up form as on this blog, I highly recommend you to check out my new ThickBox Sign-up Plugin for WordPress. I did spend a good amount of time trying to make it into a WordPress plugin so you will have to pay for it but believe me, this works really well and probably worth well beyond the introductary price of $25.
After researching many different lightbox and thickbox methods, I could not find a good plugin, so I made this Thickbox E-mail Sign-up Form.
In the beginning, this wasn’t a WordPress plug-in.
After I realized how effective the Thickbox Sign-up form is by seeing the number of my Feedburner RSS subscribers rise from 1300 to almost 1800 in just 2 weeks, I decided to develop it further into a WordPress plug-in that’s easy to install and use.

I am also willing to give out free samples to anyone who want to blog about my new plugin, just send me an e-mail at zedomax [at] gmail.com if you have a related blog that you can review on.
