If you are interested in joining a group chat, please reply, tell us briefly about yourself and what you want to chat about. We are still figuring out how to facilitate this.
For private chatting, please directly message the user and inquire if they are interested.
All chats are (apparently) encrypted end-to-end. The downside being, if you change browsers or computers, you lose your history (unless you both create & save ‘paper’ keys somewhere).
