It’s nice to see when people fork, modify and actually use your open source projects. Like Emanuel Pina does. He has forked my project MailyGo, which enables receiving form submissions on static sites and sends them via e-mail. He added some nice features (which I will definitely take inspiration from and add some back to the upstream project!).
By looking at his code I also found out that Scaleway has a managed container registry service, which might be a viable alternative to Quay.io or DockerHub.
