I am not sure what the intent of this board was. There is no such registry that I know of. Maybe the intent was to have one built but the creator ought to have have left instructions as to the intent so the users might have some kind of idea how to make use of this.
Right now this is a useless board persons post questions and no one answers them.
If you have a question regarding a photographer you need to google it. If a location is given, it is usually a town or city. You usually will have no idea what country the town is in.
