I have an ongoing Genki 1 virtual study group with a couple of Japanese native volunteer every Saturday but it’s on an old virtual world called Second Life. Personally, I think Discord or VR Chat would actually be more user-friendly compared to Second Life, but I’m just laying this out here as it is an existing study group that I’m already part of.
More details are in the link above and sorry to be riding on your post. I’m really hoping that your Genki Zoom Conference or something similar could work out soon because I think that’s a much better idea. Good luck!
