Actually its just the same with javascript and css codes for scrollbox but its kind of hard to code so i would advice that you use some sites with profile editor and myspace list of codes. i found one site with that. its http://www.ugotbling.com , they have this set of codes for myspace and you could also customize ur page and allow to site to generate codes for you and then automatically post it to your account using their gigya features.. here's the site again, http://www.ugotbling.com thank you!
