I found an active #tokipona discussion group on discord: https://discord.gg/XKzj3ex
They chat but also have voice calls to practice speaking it. I'm not ready to try to speak it yet, but looking forward to listening in to try to get an ear for it.
I am "jan Juki Towen" which is the closest transliteration I could work out for my online handle.
Amusingly, bots are all named "ilo [name]" instead of "jan [name]" which makes sense...
