Reposeed Server is a community project. From our current viewpoint, its role is: Providing a hosted version for Reposeed.
A lot of discussion about Reposeed Server happens within Github issues. Ideally, we will keep it that way until Reposeed Server becomes big enough that this turns into a problem. The advantages of this is that all documentation and issues are publicly searchable and easily linked to the source code.
The Reposeed Server project should always aim to devote a lot of time to making contributors feel like an important part of the community. We should strive to provide a place for anyone to be able to contribute. The aim of the core team should be to work on ways to showcase contributions, encourage adoption and show off great work. An example of where this worked is the CocoaPods Quality Index.
