We created a new repository for host requests for comment. It is based on the Rust RFC repo and meant to describe how major new features can be implemented. In this way more people can get involved in the discussion, without having to know Rust or getting lost in implementation details. If there is a major new feature you would like to see implemented, please consider writing an RFC first. Also feel free to suggest changes to the RFC process so that it works better for Lemmy.
One RFC was already created a few weeks ago for supporting post tags. It should be added to the repo soon.
Ooh that reminds me. Been cranky all morning...
