If you’ve never played a MUD (multi-user dungeon) before, it’s like a multiplayer text-based adventure. I’m still working on building the world, but you can join in and interact with the world and talk with others!
The server is bglinux.club on port 2860. You can connect over telnet, but I highly recommend a client. The best source of new user info on the internet is the Quickstart Wiki Page.
