Martin---I started a thread down in the GPAA Member section, Mining guide page, under the title of new guide errors.  That way it is available for the members, but the public can't drill very deep.  The staff will pull for updates from there, or whereever else they show up, but I wanted to try and keep it centrally located.  They need all the help they can get as it is impossible to go out and check each one.  If you find anything else, such as direction errors, whatever add that in and be sure to submit a report when you go out.  You can find an electronic form here on the site.
