skarpi - the best explanation would be for you to put hearme in the filter and refresh - going back about a month....but in short, if you have sound and a mic, it's a way for us to share songs "live". sort of like a chat room. people with sound cards but no microphones are able to "chat" in a text box. there is a short java download the first time you go in, then you need to change your name from "guest" (if you want to, that is) if you want to keep "your" name each time.
