Hmm, this is something i'm rather unfamiliar with as i'm coming from discord roleplaying where we usually had multiple channels or threads there, but here we're only utilizing one thread for this whole rp. However i've also taken a look around and found something like this Fantasy - New Oasis: Four Heavenly Kings — The B-Sides where they had multiple groups within one thread. So i guess we could follow their example by explicitly declaring the time and location where the rp took place as well as the participants of that particular session.
Then should we plan who's in which group beforehand as well?
