I don't have confidentiality agreements per se, but I don't want others to know who I work for. How can I prevent my clients from being disclosed?

You can hide translator feedback entries from being displayed in your profile. To do so, go to your profile page and click "Hide from visitors" in the translator feedback box in the upper right of the page.

You can opt in and out of displaying translator feedback entries at will. What you can control is whether or not *all* entries received will show. It is not possible to opt out of showing feedback entries individually.
