I don’t have a Github account after deleting it some time after it was ought by Microsoft. Given the rise of anti-US sentiment and calls to stop using their products, more people leaving Github might be a real occurrence. How can I and others who have left, are leaving, and will leave Github, be able to contribute?
Just like you can’t directly contribute to Gnome without using gitlab.gnome.org, you can’t directly contribute to Lemmy without GitHub.
Or rather, easily. If you’re submitting something simple, you could communicate with Lemmy Devs over Matrix and ask if they’re amenable to receiving a git patch they can create the PR for. https://join-lemmy.org/docs/contributors/01-overview.html
