This is primarily about being able to create milestones, but also about consistency. For example, I can currently create a milestone in the Brainstorming repository, but not in the others. As ever, this looks like a [permissions](https://docs.github.com/en/account-and-profile/setting-up-and-managing-your-personal-account-on-github/managing-user-account-settings/permission-levels-for-a-personal-account-repository) issue. It would be useful to understand who needs what permissions. For now, this may just be relevant to Manuel (owner) and myself; but will need to be understood for when others start to contribute to the code, and want to improve the code when vulnerabilities are inevitably identified. Thanks, Chris.
