For questions about the process of editing, how edits work, and other general inquiries about the edit system, used in editing questions, answers, tag wikis...

Editing is a core, fundamental part of the Stack Exchange network.

Tag usage

  • Any user can edit a post, although users with less than 2k reputation will require peer review before their edit goes live. If the question is about suggested-edits, consider using the tag as well.

The wiki for the [edits] tag on the Meta Stack Exchange site also has useful information.
