kavs,
You have neen asked in almost every one of your posts to change your name. Accounts that have invalid display names get deleted.
Your display must be your real name.
Your display name must be your first name, a space, then your last name.
You can find the Javaranch naming policy here: http://www.javaranch.com/name.jsp
You can edit your profile here: http://www.coderanch.com/forums/user/edit
Dave.
