Registration of some personal data is required before using LCG. Due to the continued evolution of the grid environment and associated access policies and procedures users will be required to re-register in 2004 and will be pre-notifed by email when this is necessary.

To register for LCG you must complete the steps described below.

1. Obtain a valid digital certificate (sometimes called a PKI or X509 certificate). (more information here)
2. Read the LCG Usage Rules. You will be required to agree to adhere to these rules.
3. Decide which Virtual Organization you are affiliated. (more information here)
4. Load your certificate onto your browser (more information here)
5. Provide the required registration information. (more information here)
6. Agree to adhere to the LCG Usage Rules when using LCG resources.

Steps 3-5 above are completed through the LCG Registration Form.

On completion of the stages described above you will receive an email containing the address of a web page which you must then visit to complete the registration process. This ensures that the email address associated with your LCG account is correct. If you do not receive an email at this stage please contact the LCG Registrar. Following this confirmation the registration process is completed by the Virtual Organisation Administration who will contact you directly to let you know when your account has been activated.
