OK Steven, I’m back.
I have installed a new market-place plugin (www.wcvendors.com) and was able to ‘stick’ the connection-capabilities to the Vendor Role. So it works !
A business-directory with a webshop for every entry that wants one.
Although I could list a couple of enhancements, you have a great plugin. I’m nearly done with the current project and will move on to new ones where I’ll use it as well.
