Clone of script

Need a script that can work in a similar fashion to [login to view URL] basically it's just a simple script that allows users to type in their myspace id, and it adds them to a "train" or a list, it produces the code that users can then post in myspace in bulletins. The list is updated in realtime as new people add themselves to the train. Just as there site has a random person to add on the page we'll want that as well. I'll provide the design for the page, you just need to have the script work within that design. I recommend you test [login to view URL] to see how it works.
