Hi Skye! Let me see if I can get an answer to each of your bullet points: 1) Yes! I have at least. 2) I found that the user had to be in Workfront in order for me to tag them after the proof has been created. If you're creating the proof and adding someone to the proof, you cannot force require login, but you can add an email address that doesn't exist in your system, and that'll add them to the proof and allow you to tag them in comments after the proof has been created. 3) It does connect to your Workfront list of users, active and inactive. I don't have anyone in my list of proof users that doesn't already exist in my WF instance, so I can't answer this one. :( 4) So... right now you can still tag the deactivated user. I believe this is an oversight, and I'd ask you to submit a support ticket so we can get more visibility on this. 5) You can go to the Proofing side (via the proofing Check Mark next to the global search in Workfront), go to Contacts, and remove a contact from all proofs, or even delete the user. There's not a way to deactivate someone in the Proofing side. Once deleted, they and their comments are gone. 6) I would recommend referring any users with questions on the various roles to the link you provided, that should clear up most confusing parts there. But yes, you do need to have edit rights to be able to change someone else's role on the proof. I hope this info helps! Dustin Martin Assigned Support Engineer Workfront
