Actually, I just noticed that what I noticed in the other thread goes away when the edit window has closed. What I saw was that this:
had this part:
as a link, that if you click on it, goes to a page where you can compare posts. I wanted to see if that happened when someone else edited theirs, but as it turns out, even if it does, you have to see the edited post within 5 minutes of the original post time, even if it’s your post. If it does work for other people’s edited posts, it will only do so within 5 minutes of their original post time, anyway.
ETA: In other words, never mind. I’d have to catch someone posting to this thread, and then editing their post, before their edit window closes, to even find out if it works that way. I’m not going to reload this thread once per minute, just to see if that link will show up on someone else’s post.
