Conditions of registration and contribution

By registering you enter into an agreement with BT on behalf of Connected Earth concerning the content, publication and copyright of any contribution you may make. Details are provided below and by registering you consent to these.

If you have any queries not covered by the conditions below please email


1. We reserve the right to remove contributions on the grounds of copyright infringement, defamation, offensiveness or other legal considerations.

2. No personal details will be published on the public website, although the user name that you chose will be visible to other registered members against your contributions to the thesaurus. We will not use your details for any other purpose or pass them to third parties without your permission.

3. Only contributions in English language can be accepted.

4. We are under no obligation to publish any contribution. The final decision to publish, either on the website or in any publicity material, rests with BT.

5. For the sake of clarity the text of contributions may be altered without the contributor being notified.

6. Any digital images contributed may need to be cropped. This will be undertaken with the sensitivity of the image subject in mind.

7. Regrettably, contributions cannot include hyperlinks to external websites.


1. You warrant that it is your own original work or that written permission has been received from a third party owner to use any other material and that you have the right to submit the contribution.

This means that you have given BT the rights to publish your contribution on the web. Where images have been copied from other sites or sources, you have written permission to use this material. If these rights have not been obtained and the owners attempt to claim damages from BT for breach of copyright or other rights, then you will be liable for all costs.

4. You and any co-authors retain copyright of your own materials and are therefore free to publish them elsewhere.

5. You grant BT the right in perpetuity to publish your contribution on the Connected Earth website at and to use it in any Connected Earth publicity material.
