One of the best (and cheapest) ways to keep in touch while travelling is to sign up for a free internet email address that can be accessed from anywhere. Gmail (www.gmail.com), YahooMail (mail.yahoo.com) and Hotmail (www.hotmail.com) are the best choices. Once you've set up an account, you can use these sites to pick up and send mail from any internet café or hotel with internet access.
