Here is the simple trick to find the friends who are online in google talk but appearing offline. This simple trick I have explained is not professional. From my experience, Any professional invisible state can be detected by this method, As this is not a tool but a hack.
Follow these steps in Gtalk to check who all are in invisible state :
- Open the chat window by clicking your friend’s name .
- Click you friends name and select “Go off the Record”.
- Send some message to that user.
- if you get the feedback from gtalk that “User is offline and can’t receive messages” in red color means that the user is really offline.
- But if you get no response that means that the user is appearing offline and in invisible mode.
