A dummy edit is a change in wikitext that has little or no effect on the rendered page, but saves a useful dummy edit summary. The dummy edit summary can be used for text messaging, and correcting a previous edit summary such as an accidental marking of a previous edit as "minor." Sending a short message via the edit summary ("SMS") is one way of communicating with other editors if there is no need to create a new thread for the message. Each edit summary can hold 250 bytes; the input box for an edit summary is limited to 200 characters. A dummy edit should be checkboxed "minor" (except when the purpose of the dummy edit is to correct a previous edit accidentally marked "minor").
