This question on the Euler beta function shows a number of edits 'suggested' by Community. What exactly does this mean? Who made the edit/edit suggestions? Why is their name not displayed? If it is possible to anonymously suggest edits, how is this done?
I asked this question in a comment not too long ago and QMechanic responded...
It means it's an edit suggested anonymously by somebody not logged in or not signed up for the site. If you log out and go to any question/answer, you can suggest edits.
