Add feature to site

******READ THE WHOLE DESCRIPTION******* Right now people can make a mp3 player with a play list for my site. BUT they cant save it. I need a cheap simple to use solution so the can save/ edit thier playlist. see the site here: trini(dot)net PLEASE PM me with you Ideas and cost. keep it simple yet functional so people will use it. I have a joomla site already ([login to view URL])maybe they can share the same user data base. so if someone is already Registered on the joomla site. the can just login and do player edits (if they made one) THANKS
