because its javascript, you need to change the address to be javascript based.. i think this is it
change
Code:
document.writeln("<a href=\"showthread.php?t="+threads[x].threadid+"\">"+threads[x].title+"</a><br />");
to this
Code:
document.writeln("<a href=\"http:\/\/www.gameshare.co.uk\/showthread.php?t="+threads[x].threadid+"\">"+threads[x].title+"</a><br />");
you just need to change the url to whichever you want to use
if it dont work, i guess its not possible to do
