Quoted from zh2oson:

robin - On occasion I come across a post that would qualify as a "Key Post" but I don't want to become an editor just to gain the ability to make these decisions. I just don't participate on here enough to deserve that designation.
So...could there be a way for users to suggest posts for "Key Post" consideration? In my ignorance, I'd see it working in much the same way the "report post" feature works - i.e., there's no guarantee that it would get booked as a "Key Post" but at least an expert could weigh in and make a determination.
For example, I'm buying a Taxi and am working through the 50+ pages in that thread to get ready. One common issue with the game is the Spinout plunge/skill shot often gets messed up. There are dozens of posts with people complaining about it not working and then the inevitable replies about how to get it sorted out properly. This post (linked below) seems to be the best explanation (43 pages in) about how to get it working properly:

As you can see...it's probably a "Key Post". The thread isn't that active, so I doubt any of the editors would ever have the chance to stumble upon this naturally.
Anyway, just something for you to consider.
I love this place and thank you for all you do to keep the hobby going.

I marked it.

Also note there is no index generated until multiple posts have been marked. So if only one post 43 pages in is marked as a key post almost no one will know until they scroll past the different colored post.
