Does not support forms

I really like this plugin, as the pop-ups it makes are so pretty and easy to configure. Unfortunately, there’s a bug where the any <form> element tags are dropped from the box – you can add a <form> tag, but inside that, any <input> tags are simply removed when you save the box.

This means that the box makes a really nice popup if you just have a link or a button to include – but if you want to include a mailing list sign-up form, you are out of luck.
