As a result of my actions herein - I have now determined what "Persona" is & am happy to allow that but want to know what & why google need to examin my email address. is this limited to my profile data only (which they are already aware of as I was registering via my gmail address) or do they drill down into contacts and other private data?? I will also research & impliment the merits of persona but desire this answer to my question before I proceed. many thanks! Mozilla Rocks! ta Damian
