Hello, sweet and spooky Trick or Treaters! Signups close in just under two days (September 18 at 7:59 PM EDT/23:59 UTC). Here is the signup information post!

And for this year's Community Challenge, we're going retro again. Your collective goal is to treat every participant.

*except for the ones who opt out of treats. do not treat them!

This will be managed in a similar style to the 2021 community challenge (see here) with percentage tiers of success. I'll post the exact tier targets after signups close and we have the numbers.

Get excited, and good luck!
