Uh, bummer. Thanks. Btw I think FEP-1b12 is the very abstract concept on how to address things to a group. I suppose we should have a working implementation of it in almost all current Fediverse software that deals with groups. The interesting part would be to specify the content that gets delivered like the chat messages this project is concerned with. Or how they're sorted, or how these groups are presented or the additional multimedia functionality.
