So @codeberg@mastodon.technology (think of it as the ethical GitHub) is a not-for-profit that depends on donations. You can also become a member of the org by supporting it.
Since I’m moving our projects there, I’ve signed up as an active member and Small Technology Foundation is now a supporting member with both me and the org making separate small annual contributions to the organisation.
If you’re using the service and can afford it, please help them maintain the commons.
