Anyone meeting the above requirements may make a pull request adding themselves as an CIP editor and adding themselves to the editor list in [CIP-1](./cip-1.md). If every existing CIP editor approves, the author becomes a full CIP editor. This should notify the editor of relevant new proposals submitted in the CIPs repository, and they should review and merge those pull requests.

I think that Rootul would be a great addition to the editor team. This is based on his past contributions as an informal editor on many of the CIP pull requests.

Would it be best to also modify the workflow in the PR, so in the case it is accepted, you can be added as a reviewer on PRs by the @celestia-bot ?
