After you create a Studio account, you will be able to add models by yourself or you can give your models (or other models that work for you) a personalized link to create accounts for themselves. So any model who creates a SkyPrivate account using that link will be automatically added to your Studio. You can find the associated link by logging into your account and going to Studio-->Add Model.
You will have permanent access to any model's account that is under your Studio, so you can make any change/settings to it.
The models who are under your Studio will have the same features as a normal account BUT the money they earn will be automatically forwarded to your Studio account.
This means that you, the Studio, will get all the money of your models. You will then have to pay your Models based on the contract/deal you agreed upon.
