Sorry @Vince44
I can't agree with you here. The only person it benefits for a host to set up their listing on their co-hosts profile is the co-host.
It doesn't matter how involved you want to be as a host and how long you want to host.
Setting up your own listing means you collect the ratings and reviews and if you decide you no longer want to use a co-host or host by yourself you have that flexibility. Your co-host can still manage your listing through your own account.
If you set up your listing under a co-host and you want to move on, you would have to start from scratch and lose all your ratings and reviews.
