Prose Fusion is a project team exploring and documenting how to do high-performance, team-based, collaborative writing. To aid our human coordination, we use tools like Markdown, Git, chat, and project management.
We have a chat channel on CSC Mattermost (free registration required): https://chat.collectivesensecommons.org/agora/channels/prose-fusion.
You can contact Peter Kaminski for more information.
