Adding Checkbox and Removing Close Button on Pop-Ups

Hello,

I am wondering if I can use the pop-up plugin to create a pop up which has a checkbox and requires the user to click it before moving forward.

I need visitors to agree to certain terms before proceeding, relating to uploading pictures.

I just need a simple pop-up that has a few sentences of test and a button for the visitor to click indicating they accept the terms and I would like to use it on multiple pages.

Thanks

Anthony
