Dear Maggie, Can you provide a little more detail? There are two ways to share a proof - one is by adding additional people (e-mails) to the workflow and the other is simply forwarding on the link you got. In the first case, everyone's comments are recorded against their name. In the second, all the comments appear to come from the same person. Which is it for you? You can disable either/both of these, and the strongest restriction is to not allow the guest (free) accounts and force everybody to log in with a paid account. Would that be an option or are you wanting to use the guest accounts? Barry Buchanan - WMA Work Management Australia
