its no problem to give registered user rights to add products. The user become the "owner" of the product. When shopping transaction is done eZ sends order-eMail to the customer and admin.
What I want is eZ sending orderemail resp. notification <u>to the owner</u> of the product. Variable persons thus and many different emailaddress.
How can this be done. I think for that I have to do modification of some php-files?
