The signup page can be embedded in a website of your own or used in a popup by adding it in an iframe. The signup page is fully responsive, and should adjust to fit most frame sizes, but example dimensions are given below.

To embed the signup page, copy and paste the following into your HTML editor. Change the src to your signup page link, and adjust or remove the height parameter as needed. You can read more about iframes and their parameters here.
