Is a conversation started with me when a buyer views licensing info for one of my designs?

No, a buyer or brand can view licensing prices right from the pattern page itself, as shown below!

A conversation is easily accessible anytime using the "Message Artist" button shown above.  Also, a conversation is immediately initiated under these conditions:

1. If the "I need a custom alteration" option is chosen.
2. If the desired license type and term require artist approval.
3. After the buyer purchases the license and returns to the Patterned site after visiting Stripe.
