Most of our websites can be accessed and used without registering your information with us. You must register with us in order to donate or participate in certain other activities on our websites. Each registration must only be for one user. Please double-check that the information you provide us is correct and complete, and let us know if anything changes. You must make sure that your password is kept confidential. This means you should never share your password or allow anyone else to log into your account. To prevent someone else from using your account, always log out at the end of your session. If you have reason to believe that your password has become known to anyone else, or if your password is being, or is likely to be, used in an unauthorised manner, you should notify us immediately. We reserve the right to disable any user identification code or password, whether chosen by you or assigned by us, at any time if we believe you have violated any of these terms.
