If u plz tell us abt it then i ll definetely participate (I have the equipment u specify ofcouse) and I think most of the ppl mite be unwilling to participate coz of that reason!
u can upload the files on either rapidshare or megauploard. Aslong as u have a microphone it shouldnt be hard at all to record ur voice. There are programs u can dl for free which give u the ability to record ur voice.
well I would luv 2 participate in this kind of gamez but I don't want people 2 get sacred after hearing my songz aur I don't want them 2 stop coming 2 MC bcoz of my songz
