A question about configuring stores...

I'd like to set up multiple stores and allow clients to administrate certain aspects of their respective stores and catalogs.

So, for example, suppose I were selling products on behalf of two different vendors.

Could I set up user accounts for each so that they could log into OfBiz and set up their catalogs (but have access to nothing else)?

I'm just wondering if there's a way I can set this up using the various role and security settings in the party manager and catalog manager applications.

Thanks. David F.
