Not trying to generate fear, but this web site is NOT using secure data packets (it's not HTTPS) so it wouldn't take much effort to have matched up those that vote'd on this ... just sayin'
I'm not really sure of the purpose of this survey ... I can understand why site vendors would be interested in this data and other's looking at the potential to sell services and/or parts, but what are you trying to "understand" here?
