"Ramakrishnan",
we're pretty light on rules here at the JavaRanch, but one that we do take seriously is the rule on display names. You can read it
here.
Basically we require all display names to be two words: your last name, a space, then your last name. Obviously fictitious names are not allowed.
Please
update your profile and fix your display name, since accounts with invalid display names get deleted, often without warning!
thanks,
Dave
