I thought it might be interesting to suggest an inbuilt chatbox on the side of the screen or Pop out chatbox that online users could use and chat while they were online.
I understand that there are other places like Discord and slack being used, but these things usually require an added program.
A pop out chat box is a feature built into Web coding (which I don't need to point out to the coding gods) But it would give people a place to hang that are online and waiting between moves or just chilling and reading. it would be a lot friendlier for people to use and connect to :)
