Nowadays, people sometimes purposely change their IM status to “appear offline/invisible”. Xeeber is a website which can let you find out who is online and who is offline. Just enter their name and Xeeber will show their status.
This service really cool as it can easily show your contact’s status by just key in the yahoo ID. But, sometimes people switch their status to “invisible” maybe they got urgent things to do and don’t want people to disturb them. So, please use this carefully and don;t disturb your friend if they really busy.
