This ability allows you to unilaterally edit posts, as well as review suggested edits from other users.
Edits should be used to improve posts, including edits improving spelling, grammar, and formatting, as well as fixes for missing alt text, broken images and links, and other improvements. Edits should, however, respect the goal of the original poster.
To earn this ability, you need to have at least a 95% approval rate for your suggested edits, with a hard minimum of 30 approved suggested edits (these numbers may vary from site to site).
