And another suggestion

Would it be possible to set up the review section so a person can post a product review and then have no further comments?

It seems to me that we have had problems, not in the actual reviews, but in all the follow-on comments.

My suggestion - Have a "one post" product review section. The thread is locked after the initial post. If someone wishes to comment further, they must start another thread in the appropriate forum section.

I'll second that.

Seems to me the product supplier should have some right to a comment. It may be necessary to explain or remedy a situation.
Maybe something like debate rules: there are only three opportunities to speak. The customer makes a statement, supplier responds, customer responds, supplier, customer and finally, supplier.
Supplier would have the final word but it would be clear how the process worked, or not.
If a promised resolution was not fulfilled, mod could add a dated post until it was met.
