I was going to suggest an edit on this question, but I don't see an edit button anywhere. I tried going to it directly, and I just get a "Page Not Found" error. It also seems to happen on this question and this question too. I don't have edit privileges, but why can't I at least suggest one?
Edit: All those have been edited by someone else now, and now I can edit them all. I'm still wondering why that happened, but I can't find more examples.
