KBtin is the one I use, partially for its TLS support (though most MUDs don't offer that). If you use it for T2T, you can connect using '#sslses t2t t2tmud.org

KBtin is the one I use, partially for its TLS support (though most MUDs don't offer that). If you use it for T2T, you can connect using '#sslses t2t t2tmud.org 444' You can also just SSH in (ssh towers@t2tmud.org), though honestly that isn't the best experience...
