The initiator of a workflow.
The Editor is an individual user who becomes the first reviewer in a workflow step. The Editor is the initiator of a workflow for a given page, typically this is the user who applies a workflow to a page. However, if there is an automatic workflow in place, then the Editor is the creator of the page or the first modifier of the page after it has completed a workflow (in other words, the user who changes a page then automatically activates the workflow for that page and becomes the Editor). The Editor is always the first reviewer in the first step of every workflow.
