You've got two options - our awesome web client or downloading a telnet client and connecting to bbs.force9.org.
Fastest way to get started: nothing to download or install. You'll have a very similar experience to using a true telnet client.
Download Netrunner telnet client, for a proper BBS experience. Netrunner supports Windows & Linux, and font scaling and smoothing.
fORCE9 is hooked up to FSXnet, Agoranet, Retronet and Fidonet. The message networks are what made BBS's so popular back before the internet forums that we now know. If you're curious, jump into FSXnet's General Chat channel and say hi!
Did you ever play Legend of the Red Dragon back in the 90s? Well you should have - it's awesome. Lucky for you we have it online - just try it. We're also hooked up to DoorParty who host dozens of inter-BBS door games.
fORCE9 runs ENiGMA½ BBS software. ENiGMA is written in Node.js, but still retains the nostalgic flair that makes BBS cool.
