Well done and rivhly deserved, brother.  That makes you a Fellow Squared.

I'm wondering if people are seeing any increase in WELL or Fitwel certification interest? Or any other 3rd party systems aimed at health and wellness? WELL seems like a higher bar and now WELL v2 offers more flexibility. Is interest and adoption of 3rd party health and wellness certs growing?

Hello all, 

Many of you have been asking about the CC reporting template for 2023 projects. It is still in-progress, but we can promise a huge upgrade from the past couple of years.
