var dropboxleft=150     //set left position of box (in px)
var dropboxtop=20       //set top position of box (in px)
var dropspeed=30        //set speed of drop animation (larger=faster)

//Specify display mode. 4 possible values are:
//1) "always"- This makes the fade-in box load each time the page is displayed
//2) "oncepersession"- This uses cookies to display the fade-in box only once per browser session
//3) "click"- Display the box when the user clicks on a link. Code the link like this:
//   <a href="#" onclick="initboxv2(); return false">.. link text ..</a>
//4) integer (ie: 5)- Finally, you can specify an integer to display the box randomly via a frequency of 1/integer...
// For example, 2 would display the box about (1/2) 50% of the time the page loads.
