 Your first PR should be a first draft of the final EIP. It must meet the formatting criteria enforced by the build (largely, correct metadata in the header). An editor will manually review the first PR for a new EIP and assign it a number before merging it.

If you use your email address, that address must be the one publicly shown on [your GitHub profile](https://github.com/settings/profile).
