An answering machine for your Instant Messaging account.

This site does exactly what it claims. I have tried this.It works for MSN,ICQ,AIM,Yahoo,Google Talk,Myspace.
You need to login with your respective account and put a status message which you want to send to the person who leaves you a message.
It works even when your PC is turned off.
