Ding is a system for simulated bellringing over the Internet. Designed for use during the current Covid-19 outbreak. It allows ringers who are remote to each other to ring as a band. Up to 12 bells can be rung as a band.
Ding also has an automated ringer, Bob. Bob will ring as many bells as you want, to any method you want. This allows a small number of people to practice ringing on a large number of bells, or even one person to practice with all the other bells being rung automatically.
