How to make the signup form pop up on a page

See https://www.riiwards.net/pop-up-demo for a demo

In order to set it up:

- Add a WiX Lightbox to your website
- Use right mousemenu items cut and paste to put the existing Birthday Club widget into the lightbox
- style the lightbox as needed
- publish the site
- when a user loads the website, the lightbox will pop up and can be dismissed

You may have multiple sign-up forms on different pages. They'll all add customers to the same list.
