With some of the clues, #8 is essentially, and ironically, public knowledge.
The clue for #9 could be described as a kick in the pants. (Trying to keep the foot theme.)

Ironically, I think we can agree that the location of day 8's piece is public.

Just remember, when you need help, look towards this group, a circle of those around you. (Clue #1)

Do you recall where you first found it?

Remember where video game hints were found, before the internet? Magazines.
They were delivered to people's homes using this method. (That is the hint for this part of the game.)

The idea is that you look in different parts of the app/site for puzzle pieces. Each piece is findable regardless of how you view the site/app. But, some might be easier on one or the other.
Each piece is worth 30 points. (Points can be used for small profile upgrades.)
The main objective of Read more… the game is to encourage members to interact with the app/site and each other. Plan to look in places you probably only glanced at when you joined.

I know this is Fet and all, and being transgressive is a thing.
But, it is not even Thanksgiving, and you are starting up a Christmas thing? Too far. Just....too far.

Just grabbed the last 2 pieces.
Visually, this has been my favorite puzzle.
Having each piece be an individual item made it feel like a scavenger hunt more than a puzzle. And, the completed image looks like the inventory screen from an RPG.

There is often some weirdness to time stamps in the US.
I have seen threads missing several recent hours of updates. (And, as a result, I have replied to comments that were hours old and already addressed.)

There are two ways to get to that one on the app. Not sure about the site.

All games have these, as do most groups. They are often codified.

I understand the clue for #19. But, I cannot get to it on the app.
