I'm surprised someone hasn't mentioned this seeing as you've posted quite a few times, but your display name is not in accordance with our naming policy. Please take a second and edit your display name in order to comply. The gist of the policy states that you need to have a "first name" followed by a "last name", which could also be read to mean a "familiar name" followed by a "family name". And as the policy states, "you can even use initials for the first name if you like." So in your case, simply switching your display name to "R Kumar" would be in compliance.
