    Uh, I don’t see anywhere HOW to use this PI. I downloaded it, activated it, set the options but now what? Does it create the form, do I copy/paste a text string in my current forms, etc.

    I read over and over just DL and activate then choose options! Okay. and THEN what? How do you actually apply it to your forms? Is there anyone out there that can explain NOT how to DL and NOT how to INSTALL and NOT how to set the options but how to go from hitting Save on the options menu and actually using it with forms?

    I’m guess I’m surprised that others don’t seem to have a problem.

    NOT A PLUGIN FOR HEAVY SITES!!! The code should be reviewed before thinking about using this plugin. We used this plugin on a site that gets hit about 15 times a min, with tons of unique sessions. The problem is that the plugin creates a session for ever user that hits the site and uses the PHP file session handling which is pretty slow and over time you will see performance issues on your website. There is no reason to create a session when someone hits the site and isn’t even viewing a captcha.

    //runs every time wordpress is loaded
    add_action(‘init’, ‘wp_captcha_init_sessions’);

    //runs this function every time
    function wp_captcha_init_sessions(){
    if(!session_id()){
    //creates a session for every user that hits the site
    session_start();
    }
    //…………………
    }
