Vendor rating forum
 

I think you should be able to change your vote on vendors. I had once received good service somewhere but since I have gotten poor service. The poll can't reflect the true ongoing service.

I agree however the software doesn't seem to allow for that. I wonder if "resetting" them every year would help??

"might"

I think that is a good idea since places can change a lot in a year

Yep a yearly reset would be a good idea.
