Site registration and your username and password

Where you are invited to register or login on the Site, you may be asked to provide specific information and may be allocated with or may be asked to choose a unique username and/or password that gives you access to your Site account. You are responsible for maintaining the confidentiality of your username and password, and are fully responsible for all activities that occur through your Site account. You agree to immediately notify us if you become aware of any unauthorised use of your password or Site account or any other breach of security. We cannot and will not be liable for any loss or damage arising from your failure to comply with these requirements.

We normally show your name or username (and school if applicable) with submissions you may make to the Site unless you request otherwise, but for operational reasons this is not always possible.

We may refuse to grant you a username that impersonates someone else, is or may be protected by trademark or other intellectual property rights, is offensive or otherwise inappropriate, as determined by us in our sole discretion.

Information you provide to us as part of our registration process will be treated in accordance with our Privacy Policy and Cookie Policy. As part of these Policies, we may use your personal information provided upon registration to contact you with more information about the Site and any of its features or services. We may also invite you to participate in surveys and discussions via online and offline surveys and discussion forums. We also use personal information in aggregate form (so that no user is identified by name) to audit how the Site is being used and to help with our strategic development of the Site. Participation in surveys and discussion forums is entirely voluntary. You may unsubscribe from being contacted for these purposes at any time by letting us know by contacting us using the contact details provided at the end of the Terms and Conditions.

Any communication or material you post, transmit, or distribute to the Site by electronic mail, through interactive features of the Site such as a discussion forum or blog, or otherwise, including any images, data, concepts, know-how, or other content, questions or comments (collectively, the “Contribution”), will be considered non-confidential and non-proprietary. You retain copyright in your Contribution (so you may continue to use your material you contribute in any way). You grant to the University a world-wide, royalty-free, irrevocable, perpetual and non-exclusive right and licence to copy, reproduce, modify, adapt, translate, broadcast, transmit, display, perform, rent, lend and communicate to the public your Contribution in whole or part in any form, media or technology now known or hereafter developed. For the avoidance of doubt, this licence will be free of charge, perpetual and capable of sub-license. By submitting a Contribution you acknowledge that you waive any moral rights you may have in it.

If the Contribution is made available to the public in the Site, you grant other users of the Site a limited licence to use, store and distribute your Contribution and make it available to others, without your permission, in any medium throughout the world.

We normally show your username (and school if applicable) with contributions you may make to the Site unless you request otherwise.

If you do not want to grant us these rights, please do not submit a Contribution to the Site.

You must not establish a link in such a way as to suggest any form of association, approval or endorsement on our part where none exists.

Our Site must not be framed on any other website.

Third party links and resources in our Site

The Site may contain links to third party websites. The University has no control over the contents of those websites or resources and accepts no responsibility for them or for any loss or damage that may arise from your use of them, nor does the inclusion of any link in the Site imply our endorsement of any website or any association with its operators. These third party websites and resources have their own privacy, copyright and terms and conditions and we urge you to review them.

Notice and takedown

We have made reasonable efforts to ensure that the reproduction of material on the Site is done with the full consent of rights owners and/or in accordance with relevant legislative provisions.

The University may immediately suspend or terminate your access to the Site without notice if any breach of the Terms and Conditions by you is brought to our attention. The Terms and Conditions shall also apply after your registration is suspended or terminated.

We exclude liability for actions taken in response to breaches of terms in the Terms and Conditions.

If any of the terms of the Terms and Conditions should be determined to be illegal, invalid or otherwise unenforceable by reason of the laws of any country in which these Terms and Conditions are intended to be effective, then to the extent and within that jurisdiction in which that term is illegal, invalid or unenforceable, it shall be severed and deleted from the Terms and Conditions and the remaining terms shall survive and remain in full force and effect and continue to be binding and enforceable.

Third party rights

Nothing in this agreement shall confer on any third party any right or benefit under the provisions of the Contracts (Rights of Third Parties) Act 1999, meaning that the Terms and Conditions do not create or infer any rights that are enforceable by any person who is not party to the Terms and Conditions.
