Clarification of Question by sugran-ga on 18 Mar 2003 08:23 PST

I have elaborated my question quite explicitely.
The Two links you provided are useless to me.
I can do a better search on Google Search engine
myself. I have paid Google to carry out proper
search for me.
What Clarification you want, you have not asked any?.
Could you please read my question carefully and address
it properly?. Ask me a definite question please which
you want me to carify.
You links answere nothing.

Sugran,

You may not be aware that you are not actually charged until an answer
is posted. If the links googleexpert-ga provided are not helpful, they
have cost you nothing beyond the $0.50 listing fee.
