Monochrome (www.mono.org) is a #TelnetBBS which is still active after over 30 years.
Giving it a little boost here to see if there's interest. So if you were a fan of the #BBS and the communities that they fostered, have a look.
Mono was started as a student project at #CityUniversity in London, then became an internal social network, before being opened up to externals and the wider world.
Makes great use of colour, fast to navigate, read and post, and included it's own ASCII animation language to allow for rich utilities, games and dynamic topic sections.
