Tracking who edits a document
If a document contains an Authors field, Domino® Designer automatically stores the names of the users who have edited that document in an internal field called $UpdatedBy. Servers involved in replication are not considered editors, so they're not tracked in this list.
To display the contents of the $UpdatedBy field, users can click and hold the cursor on the Authors field in a document they're reading. Designer displays a pop-up list of everyone who has modified the document, including people who did so through agents. Adding pop-up text to the field label helps users understand the list.
If a form is assigned the "Anonymous form" property, its documents do not contain an $UpdatedBy field; instead, the documents contain an $Anonymous field with a value of "1."
