I prefer original code that we can own, without adding credit to other sites.
I want this on-click popunder to work once per browser session, or once per day.
I have collected a few chunks of scripts from different sources that do various parts of this, but putting them all together and making sure they work with modern browsers if beyond my scope of code splicing. I can send you urls and examples I have found.
I need to know that you are 18 years old or older to work on this project. Please quote me a fair price (I am assuming this is less than one hour of work), and estimated time of completion.
