From their book address in Yahoo! Mail. Your icon will still be yellow as Yahoo! Mail doesn't have stealth feature like Messenger.

You can't. That's the point of it being 'invisible'.\n\nThat person can contact you if they want, and then you'll know they're on-line (that is - if you're not invisible...)

The only possible way has been answered. You have to appear invisible to all. \n\nBut then again, if the person who's trying to track you down wants to really track you, he can use "Buddy finders" which tells any one if any buddy is online EVEN IF THEY ARE INVISIBLE. !\n\nso, there is actually no way.\n\nif you don't wish to receive IM's from people who are not on your list, then you can change your preferences to receive im's only from buddies on the buddy list. !

From your yahoo mail, just click on the address. If the smiley icon is yellow, it means, your friend is online and if it is gray, he is offline.

You are signed into your yahoo360 page but you are not online.  Try signing in to Yahoo Messenger and then go to your Yahoo360 page and you will see that you are online.  Seriously though, this is a slighly brain-dead question. Obviously, if you are not online, you  will not show up as being online...duh DUH duhduh!  Too much television, too any video games, all this contributes to the problem.

If they are invisible to everyone, No there is not a means to find out. If it is just to you, open their profile. It will say they are online if they are. Sometimes using the Member Directory Search will tell you, even if the Profile doesn't tell you.

What's most probable is that either some aren't online, they're blocking you, or they are online and just put they're status as offline. You can get Blockchecker for MSN if you want to know if they're blocking you.

Hi there :)\n\nSadly you cant.   You can send them messages which will appear as offline messages to you, but they can be sitting behind their screen knowing who is online.  I dont like invisible.  Even when you do a search, you wont know if they are online or not until they go offline where you do get a so and so is offline box.  \n\nHugz\nscorpz
