> How do suggested edits get approved?
Two accept or reject votes are required to remove the suggested edit from the queue and either apply the edit to the post or discard it. It used to be a single vote (two on Stack Overflow), later three on SO, and then later still SO was dropped back to two to match the rest of the network.
If a user votes to Improve Edit or Reject and Edit, their review will dequeue the edit, as the Community user will make a review (see below).
