I have a modal pop-up that appears when a user visit my page. The code is here: http://pastebin.com/jRAgu7ZS
This is what I need:
When the users click the Close button I want it to disappear for ever, preferably even when they close the browser and start a new session. It should only be visible once. It should show on the first visit, but when it's closed it should never appear again.
Payment by PayPal and I need the script before in a couple of days.
