How can i know if my friend in yahoo messenger is invisible or offline?

Cast Drain Life and make sure you have radar turned on.

signing in as invisible is a reason that the person is hiding from someone or you. so you don't need to force yourself to know if that person is really online but just invisible. but if you want, you need a program to do that, "buddyspy" is good. *sending a "Doodle IMVironment" is not a solution because if the person will not accept that IMVironment, it is useless. i had tried it using different IDs and different computers at home, it is just keeping "Waiting for the Friend to accept it". and i had tried it on both invisible mode and not online simultaneously. even the voice chat is no longer active for that. yahoo had changed everything to protect the privacy of any user and that's the reason also that they are having the feature of "Stealth". *at any rate, there is another way, but i can't disclose it here, sorry.

You cannot know...that is why they get invisible ...to think the rest they are off line.But if you text him and he replies to you at the same time then he is invisible....

use the doodle imviorent if it loads then ur friend is invisible
