Need a little help im making a adult site with wordpress and wp is installed in the main dir. The main wp file is index.php. What i need to do is have a agree disagree page which covers the index.php until they click the agree button. I don't know what would be needed a script some kind of layered pop up which cant be blocked? I have seen where the page is greyed out almost in a dark transparent way until you click the agree button on some sites but i don't know what it would be called. Can some one help me figure this out?
