I was checking out the massive amount of settings this forum now has (really neat) and I noticed a setting called Thread Display Mode which had a number of different settings in the drop down.

After the drop down selections was a part that said:
Here you can choose the display mode for threads. For a full explanation of the modes, please view this help page.
Which then took me to a "Invalid FAQ Item specified. If you followed a valid link, please notify the administrator"

I know you said you're still working on the FAQ, but I wanted to call this one out since it's pretty buried and could be easily overlooked.
