ra, let me try to explain your question, as I see it. People were putting puzzles in various threads so in May of 2012
Nora got a fine idea and posted this, starting a new thread in the Decorah Lounge. As everything else there it was off topic relating to the Decorah Eagles. I think the original idea was you could add puzzles under your name and some of us did (see page 1 of the "Puzzles for wild cam addicts" thread- Iver removed his list of puzzles)
Here's a thread for Iver and anyone's puzzles so we can find them all
In 2013 the chat moderators started two threads an education thread and an entertainment thread. Faith started it off with this post.
This thread will be for puzzles, games, and fun facts. I will start it off with a jigsaw puzzle. This is a screen cap I got on 1/10/2012 of a Decorah Eagle parent's talons. An eagle's toes are numbered as follows: The back, rear-facing toe (the hallux) is #1; the innermost forward facing toe is #2; the next toe (the middle one of the forward toes) is #3; and the outermost front-facing toe is #4.

I think it was meant to be built around the topic of Decorah Eagles but little has been posted there except jigsaw puzzles. I am careful to post only eagle picture puzzles in that thread. All other puzzles I post in the Wild cam thread. That is my understanding but I have been wrong before.
