As far as I know, there's only one administrator, Andy. Neither of the past moderators, Tom or Mark, appear to have been around recently.
I found it interesting that the update tripelo requested was actually made, perhaps it was an automated update from the original FCC data base. I've submitted change or update requests over the last several years, the recent ones of which have not been done. Updates for San Diego, for example haven't been done and its been three years since the analogs were all switched off. New York City still has the wrong location for a number of the stations.
