i have had msn for a long time i have not sent a messege before and it neaver got to who i sent it to i admit sometimes it may log me out ramdomly or refuse to log me in but thats not offen and it is free so i dont expect too much off it the voice on it thow is not seem less thow on things like Seconed life i get away with 80% of the time hear tham really well i do have yahoo but i have not used the voice on that so i can say how good or not it is but atlest with msn you dont have a lot of windows open at ones like with yahoo im not saying one is bad it is just other ways of doing things but for me MSN is good i just use my cam most the time i dont voice that much anyway
