I just joined the Codeberg e.V. as an active member.
The mission of the Codeberg e.V. is to build and maintain a free collaboration platform for researching, creating, archiving, and preserving knowledge, code, and to document its development process.
I really like Codeberg and its mission and use the platform for some of my projects. Today, a fellow student / colleague asked me a few questions about it, then joined himself. That inspired me to actually join now too, instead of sometime in the future.
