Harvey has a small group of enthusiasts that spend their free time on it, looking, experimenting, testing… but in order to keep things on track, there is a small group of people we usually call “core team” making decisions on what gets merged. These people know the system well and are a good resource if you have questions. You can find them on the Matrix space or the mailing list.
Come and meet Harvey! it’s a lovely rabbit (in case you could see it).
