Hello there!
I have just created /c/newcommunities@yiffit.net to help local and remote users stay on top of communities that are created on Yiffit.
This is especially important for NSFW communities because remote users have no way of accessing them as they don't appear on our homepage unless a) they are logged in with a Yiffit account or b) someone at their instance has made this community available.
The idea for !newcommunities@yiffit.net is that community owners will be able to announce their newly created community here.
Over the coming days I will back-fill all existing communities so that users will have a list of all Yiffit communities. If you are the owner of a community at Yiffit, feel free to announce it at any time.
Cheers!
