My plan is to have stores rated numerically in three categories; Value, Selection, and Service. These 3 scores will make up the store's overall rating.
Users will be able to also post their experiences.
Users must be registered on the CAG message boards to be able to participate and IP addresses will be logged,
Sounds good, but you should make the section to post experiences flame proof. The last thing this idea needs is people fighting over whether a sites service is good or not.
