...and if it is just for your familly, friends and colleagues maybe what you can do is give the URL of your web-site only to them and put a robot.txt file in all your web-site folders (usually in the public_html folder) it cannot be searched by Google, Yahoo, etc.
My contacts can already be reached by email, so it's not really a problem, although it could be fastidious and worse, ephemeral. And I would like the website to be searchable by google and others to get more contacts from the web community.
