Do you realize you have obfuscated Javascript on that site which injects an iframe that points to a Wordpress site on eigenmembershipsite.nl? The easiest way to do what you want to do is to use PHP to set and check for cookies that would contain the last time they visited whatever you want them to see. You can keep a text file or something with the date of the last update, and PHP can check the date in their cookie against the date in that text file to see which is newer.

Which part did you not understand? You'll need to use PHP for this, so if you don't know PHP then you'll need to look how to manage cookies and read files with PHP.

I'm also interested in how the spinning circular progress doo-dad is generated. Is that a sprite?
