I keep thinking that any reply detailed enough to "teach" how to do a thing deserves being saved as a "tip" with screenshots. Or maybe a thread buried in the "Site Talk" forum, with each "tip" as one post in the thread.
Then we could star each post in that thread, and be prepared to answer any question about using the site with just: "Here's how ..." and a link.
And the thread itself would be a resource for ambitious users.
I started saving screenshots on my PC, but finding them at need was too slow.
