Perhaps he is not online or set his online status to 'invisible',he could do this maybe to restrict disturbance or trying to avoid you.
With this free service i'm about to introduce to you guys,you can detect the online status of your friend if he is actually offline or just wants to avoid you. Interesting isn't it?
What i'm about to Introduce to you is a free service called YDetector .
It is used to bypass Yahoo's Invisibility Settings and Reveal the Rerson's true Online Status. Its user interface is highly interesting and friendly.
Just open your Browser, Type in www.ydetector.com as your web address. When its open, type in your friend's yahoo ID (without the @yahoo.com), and BAM!! Your friend's online status is exposed.
