We are developing a new open online marketplace where people can share their knowledge solving Q&A using video streaming, and where they can charge for the time they spend talking on the conference. The topics can be extensive from translations, classes, lawyers consultations or any type of sharing that can be made using video streaming. 

Is there any liability as owners of the platform that we need to be aware of? regarding responsibility between the two persons and their business?

We appreciate all your inputs.
