Tumblr Logged In Checker

This script allows you to check if a user is logged in when they visit your blog by intercepting Tumblr's internal analytics' iframe messages.

You can use this script by defining the following functions in your Tumblr Blog's HTML

var is_logged_in = function(){
    //What do you want to do if the user is logged in?
}

var is_logged_out = function(){
    //What do you want to do if the user is logged out?
}

Then include the script file into the HTML

    }

    var is_logged_out = function(){
