@Chris Levitsky - if you ONLY want your clients to review/mark up Proofs, what we do is only allow the clients to access proofs they need to review, through the Proof email that gets sent to them. We do set up the client in WF (so they have a proof account, and our PMs can add the client to the workflow) - but they don't have a login to Workfront at all - since we check the "Only Allow SAML" option, and the client isn't in our active directory - so they can't actually log in to WF and get to the project or documents (which is what we want/need). This also ensures the client can only see that particular version. Katherine Haven, PMP VP, Director, Business Technologies - PMO FCB
