text: as long as you are using free public email systems like yahoo, you can check your email anywhere.  if you are using a corporate email,  ask the administrator if the system is web-enabled.  if it is, ask for the web address of the email system.  using a web browser, use the address given by the administrator to login to your account.  you can now check your emails.  one more thing,  if your email system is set to downloading your email locally,  you cannot access the downloaded email from your other computer because it is already stored locally.
