We are pleased to introduce the launch of our new website dedicated to the Fediversity project.
|
||||
|
||||
The project is broad in scope, and the website reflects this. Whether you are a developer, an individual interested in the project, or want to know how the grant money is spend, the website keeps you up to date with everything you need to know.
|
||||
|
||||
We're excited to show you more of the progress of the Fediversity project, and how we can build a next generation of the open internet together!
