Marketpress – Prosite

Hello,

So I have Multisite, Mutilsite Manager, marketpress and prosite running on my site.

How do I go about giving access to the new subscriber to have a store? and manage their products.

Also – with the different levels on prosite – am I able to for example give Level one access to list products for free, but level 2 would have store and would pay a fee?

Thanks.
