Not having seen your work prior to Challenge 8, your report was an unexpected lightning bolt, and the accompanying writeup was equally great. Excellent to see your work get recognized in this way, and hopefully provides an incentive to get others watching and sitting on the fence to jump in and begin participating in the challenges.
I’ll be in touch by DM about getting you your prize. Here’s the thread with your choices:

Congratulations on being the inaugural “First Timer” award winner.
