Check whether an existing VO will meet your needs. The full list of registered VOs can be found on the CIC Portal. If an existing VO meets your needs, request to join that VO rather than start a new one.
Review the documents (listed below) related to starting and running a VO.
Identify a person (possibly you) who will act as the VO Manager. This person will approve requests from people wanting to join the VO.
Ensure that the person who will be the VO Manager has a personal certificate.
Using his or her personal certificate, the VO Manager should register the new VO via the CIC Portal. This process will require a description of the VO, an Acceptable Use Policy, and a DNS-style name for the VO. You may request the necessary VOMS server during the registration.
