I have sent him 2 PMs and email. He didn't reply to either of them, but his profile shows that he was online after I sent them.
I received your 2 PM's today morning (10.30 AM - India). And i Replied Today 3.30 PM (India). The time gap is only 5 or 6 Hrs.
And Yeah My Profile Shows Always online. Auto Login when i start my Firefox From Morning to evening. But i can see the PM's only when i start browsing WF
