In standalone format RP seems to only show members that have added products in /showmembers.php.
It'd be much better if it showed users that have uploaded just reviews too in that list.
Line 123 of the code:
Code:
Content visible to verified customers only.
The basic SQL only selects members that have uploaded products (it deals with the products table) rather than products & reviews. I'd suggest a rewrite of the SQL there.
