Q: Where can I find the commercial, partner extensions?
A: To find the commercial extensions you need to go to eZ Market. These are the certified partner extensions ready for sale from the eZ application store. Note that these extensions are only available to you as an eZ Publish Enterprise customer.
You find the community extensions on a separate page called "The Community Contribution Corner". Note that you will find the official, bundled extensions per eZ Publish version on the Community Portal download pages.
