Enter any YAHOO account name in the field below
and press the "Check" button to find out if that person is
online or offline. The YAHOO image should change to one
of the below status icons. If it shows the online icon and
you've added the person to your contacts but he or she ISN'T
listed as online, be sure you're being blocked by him or her!

What does it show if the user is in invisible mode? It will show them Offline.
The Yahoo Status Checker is a tool, some people call it with different names.
It actually shows the status of a person, if that person is online according
to Status Checker and offline in your Yahoo Messenger, that means he/she has blocked you.
NOTE: Status icons are as fallows: Online = Offline = Unknown =
