I hope that I have found a system that can give unbiased ratings of horse trainers by location. I developed another blog called Rate the Horse Trainer. On it there will be nothing but polls that you can either vote on horse trainers or if you are looking for a horse trainer, view the poll results. I have tried to list as many scenarios as possible (the poll would only allow a max of 9 answers) to cover what might happen with a trainer and a person's satisfaction with them.
Many of the trainers listed on this blog have already been added. The polls are set up to only allow one vote each so I hope that stops fraudulent voting by the trainer themselves. Please visit the blog and see it in action.
