This Repl runs a client for a Bulletin Board System (BBS) hosted at https://replit.com/@mattiselin/bbs-server.
It's a full terminal client - no webpages here. Behind the scenes it uses a websocket to talk to the server (because you can't telnet to a repl).
If you're logged in to Replit, it should pick up your username automatically. Otherwise you'll be logged in as a guest and have read-only access.
