Warning: Avoid editing other people's posts. StackOverflow's policy is that any edit that does not fix all issues in the post is "too minor", so if your edit is deemed to not address all issues in a post, even if it is otherwise correct, it may be rejected.

Warning: Avoid reviewing edits without fully reading (including linked documents) and understanding what is being edited. If you approve an edit to a post that is later closed, your editing privileges may be suspended.
