If you are a mod on an active community hosted on Blåhaj Lemmy and would like to join our matrix room, please send me a DM with your Matrix ID
This room will mostly be used to aid moderation, but also to give space for communication with the admins etc, however all of the existing contact channels remain as well
What is Matrix?
https://matrix.org/
It's a decentralized messaging protocol, like a fediverse for instant messaging.
I'd say more like federated discord than IM.
