Hello, After the initial testing period, we'll be deploying the GCO sign-off hook to more git.g.o-hosted repositories. To reduce potential problems, the hook will be deployed to groups of repositories. If the hook misbehaves or shouldn't be enabled for a particular repository (could be a case for repositories with autogenerated and/or non-copyrightable content), please file a bug. TIA! -- Best regards, Michał Górny
