ASs has been said, all users have an email link nest to their names - although their email address is never revealed by us.
If you are planning to mail another forum user please stop and consider before doing so. Is your message really necessary, and would you like it if you started receiving messages from complete strangers? We have included the links because there are occasions when they come in handy - when exchanging confidential information for instance, or when one user sends a file to another by request. In the main however, we didn't intend to provide a means for anyone to mail anyone else on impulse; such messages could be interpreted as an invasion of privacy, and we would urge you to use the mail link only when strictly necessary.
