Janus 2-seat glider as a club glider?

.... *The hand wringing about flaps is amusing. *Every airplane trainer
these days has flaps - and, of course, an engine to manage. *Come to
think of it, gliders are probably the only aircraft still manufactured
without flaps.

I've wondered about that too. I'd never flown a flapped ship until I
bought one. It didn't seem to be very complicated at the time, and
still doesn't.
