Shoutbox

Tweet

someone knows how to do a shoutbox or something like that to let the users from my site make request content that they like but I don't need only one I need different one for each category (music,videos,images,wallpapers,tutorials,downloads,earn money); and I don't know where I can find a service to do it or the code to do it myself if someone have a suggestion or know how to do it I would appreciate it
