Six or eight new support threads in a matter of 5 minutes from one individual *is* a bit much. ?? Easier to answer everything in one topic, because www.remarpro.com doesnt let us reply as fast. It tells us “Slow down, you move to fast” and we have to wait a minute before the next reply. Just unnecessary time sink is all.
With WC Vendors, of course, vendors can sell stuff. That’s the whole point of the plugin. ?? As for “trading” — If you want someone to say “I will give you X if you give me Y”, then that’s something you would have WooCommerce do, not WC Vendors, as that’s likely a WooCommerce third party plugin to support a “trading” product of some sort. Not sure if any exist like that, wouldnt surprise me if it did already of course.
