Dear @Stephen
Thank you so much for your opinion.
For this question, at least site operator have to reply to sell their products. As you know Woocommerce is very limited, so I would like to make a limited best solution for wordpress and woocommerce.
I think Woocommerce question and answer function is needed for better customer user experience. For discourse, I will use as community function, so it is also very meaningful.
Thank you.
