Deleating and Remaking a Screen Name in a new account?

Yahoo is the only online community I know of which allows duplicate use of the very same screen name. That goes for YA and for the messenger too. Very few users are aware of this problem, so unless you create a truly unique name, you and/or possible contacts may encounter problems. Suggestion: create a screen name -> go to Google -> enter your screen name followed by "yahoo profile". If somebody is already using the name, you'll find his profile in the Google list, by adding some numbers you lessen the chance of duplicate screen names.
