Even though you can set the project status to appear in the Update feed, it's not always populated correctly in the Notes so we can't report on it. We should be able to create a Note report that shows all project status updates.
WF built me an "Update Export Request. Is a report that shows the Task Name | Entered By | Audit Text | Note Text |Entry Date. It captures data from the project and the proofs. Hope this can help.
Column 1 = Task Name
Column 2 = Entered By displayname=Entered By linkedname=direct namekey=owner:name querysort=owner:name textmode=true valuefield=owner:name valueformat=HTML
