This box isn't about her; she will have the chance to complete her bio once her registration has been approved. This just helps mfc to decide on your application.
Describe any past experiences she has had working in the industry, specifically on cam. You can mention the type of cam shows she will also be doing and how many hours she intends to work. I cannot imagine this box is too important. I think it's rare that mfc denies a registration; if they do, it's more targeted towards the performer's location/nationality.
