Does years of using email make people blasé? I constantly receive emails with the list of recipients for all the world to see - spammers, fraudsters and all the other folk in search of insecure accounts.

The Blind Carbon Copy feature seems to have passed a lot of people by. It's easy to use. if you're sending a round-robin email then make the 'To' address your own. Underneath you'll see the CC and BCC boxes. Put everyone else's email in the BCC box. That means their address will be hidden from undesirables. Apart from your own, of course. (Well, nothing's perfect.)
