A new version was deployed today 22nd of March 2004. It fixes minor bugs and adds a new feature to the service. Now when users get online and (if) everything went ok a "Welcome online" message is automatically added to your message stack. The sender is "wv:yamigo" or "wv:yamigo [at] yamigo.com" depending of the device implementation. Both should point to the same user. This is a valid address. It can  be used to send messages to admin. We'll try to reply in a timely manner (if during the Europe's working hours GMT + 2h).
