I've decided to change the communication protocol used by the mikedamage.info chat server from XMPP to Matrix.org. I just finished setting up a Matrix instance on the chat server, and it's ready for some intrepid guinea pigs to kick the tires! There's a long winded explanation of why I'm switching us over to Matrix, but I put it below the instructions in case you don't really care.
TL;DR Matrix is easier for me to manage, more secure for you, and everybody can access the server using same app, with the same awesome features, on pretty much any device or operating system in existence.
Coming Soon: Once I set the Matrix server up properly, we'll be able to do real-time, person to person voice and video calls in addition to text chat!
