Someone has organised a Lemmy version of r/place at https://lemmy.nz/post/741632
The site uses your lemmy account, but doesn’t require your password. Instead it will send a message to your lemmy account to verify it’s you. I had to try a couple of times to get it working but it worked in the end.

I’m far too disorganised to coordinate that. Though I’m sure someone from /c/Melbourne will 🙂
