Disboardia
Welcome to Disboardia! Before the internet, we would go online by calling bulletin board systems over the phone with a modem. I had so much fun running one in the 90s, that I decided to bring it back. It even runs WWIV, one of the software packages I used. The BBS has interesting message areas and games.
Accessing the BBS
Note that telnet does not have any encryption. You should use SSH if possible. Once you have an account, you may substitute your user name or number for bbs as the SSH user.
