Recently, I just applied the Streamyx 1.0Mbps. I found that I'm very difficult to sign in MSN. Some of my friends are also experience this problem. Thus, I have find the alternative ways to sign in MSN. There are some website provide this kind of services such as Ebuddy.com. But, I don't very like it because of it's interface. I found another better website. It is ILoveIM.com Web Messenger and Meebo.com.
ILoveIM.com's interface is more user friendly. Other than that, it also connected with Yahoo, AOL and Gtalk messengers. If you have experience same problem like me, you can try it out.
