My personal opinion is that if there is an open repeater which does not do anything to hide PL, e.g. input equals output, it should be listed regardless of the owner's desire. It is an OPEN repeater.
Prohibiting anyone but owner to list OPEN repeater makes myGMRS site usability very questionable to say the least. I came here for the sole purpose to see if several really OPEN, input equals output, repeaters I can hear around me are listed on the site and they are not.
I believe that there should be a way for anyone to post OPEN repeater information and give all users ability to confirm its status if they can access it.
