Chat plugin: Is there a way to NOT show a chat as comment

Hi, I've donwloaded Support System and Q&A. The later is excellent for creating a FAQ and answering questions. The first gets people into the dashboard, and I'm not interested in that. So I'm trying to see how I can allow clients/members to POST private questions. These questions are for our service providers in the Appointment + plugin. Can people post questions using chat that will not be displayed? If they can, how can I set them up. (I just don't want to download something else if it's not going to do the job.)
