I submitted my site to google local on last week of jan, 2006. After all the formalities I got this message:
First you'll need your PIN, which should arrive in the mail within two weeks after you submit your business listing. If you have your PIN, enter it beside the appropriate listing below, then click 'Go.'
Its a pretty simple process I guess. But its been more than 45 days and I am yet to get a PIN number. I requested another letter which I am yet to receive.
