Searching for people's addresses can be a disappointing activity.
Databases are incomplete, especially for email addresses.
This is partly due to people's desire for privacy which leads them to have unlisted phone numbers and to keep their email addresses off search engine and other lists. I did install Alexa as I was curious and it worked. I really like it because it gives me instant access to links which I might not think about. Immediately I got a selection of items, pictures, dealer's nameand number and email address. A German engine, in german.
