I've got to agree with Hee-Hee. While I can understand where you're coming from, KoriStarfire, the list's main purpose is to be used as a reference for people who wish to judge the quality of a commissioner's work foremost. The grades are meant to be a combination of customer service and final product and overall experience, and receiving a poor grade before money was ever exchanged or mentioned might give potential customers the wrong idea.
I've had countless instances where I've received one or two emails in response to a quote request and then sudden and perpetual silence, personally. Just a part of the package, and certainly more a loss to the commissioner than the customer enough as it is.
Also, thanks for the clarification, AkaneSaotome. The two listings have been combined.
