Hi Steffi,
Thanks for the help. I can see the details now.
But those points are never awarded to me, you see. Those people must have clicked on star rating and SCN awarded me -2 for each like ? 
At least it should be converted to a UNLIKE icon so that every one will become aware that it has been a rejected blog? I don't get the logic. I suppose, SCN is missing out on this point.
Regards,
Naveen
