So I was looking through my general topic, and I wanted to see the last time people on my tag list have been on, and when I wanted to check @braybraylovesmonkeys, I couldn't click him/her. I scrolled down to their last post on the topic, and I couldn't click it either. Because I am on a desktop right now, I checked by clicking "Open in a new tab" and it said the page didn't exist.
(sorry my writing is so messy here it's just hard to write by clicking with a mouse)
The command for taking a screenshot is (Windows symbol)+alt+(prt sc button near the keyboard corner on the top row)
