Great thing that there was much less vandalism. I was able to single-handedly put my work on there and didn't have to fix up anything at all.

The chat wasn't working for me. There is a hotkey ('B') for that but nothing appeared for me and I don't know if something was wonky on my end. Would be nice to be able to easily communicate with other peeps during the event.

for next years I would like to better connect the on-site chat with Matrix

That would be great!

oops, didn't see the other thread...

done that! :D https://toast.ooo/post/289361

For me the cooldown was 30 sec when I placed a pixel on a blank pixel (not placed by anyone before) and 60 sec if there was already a placed pixel.

It basically does what awk '{print $3}' in your command does, so it just gets the users. It was quicker for me to do that right out of the top of my head :D

I've written a Lua script now that should deliver more accurate results and edited the post. Though I'm not sure how to interpret the "mod overwrite" actions, so I guess that would count as a moderation action that would decrement the user's place count.
