Parabola uses the Libera IRC network, which is dedicated to supporting free-software communities. You may also use Matrix or Freenode to connect to the main #parabola channel (conversations will be visible in all three locations)."
If you do not have an IRC client now, you can use a web client in your web browser to access the main Parabola IRC channel. The primary languages are English and Esperanto.
#parabola: general discussions and help.
