Hello,
Update Geocaching.com to allow personal notes to be added to cache pages. For example, if a user completes a puzzle cache that is not at the "Posted Coordinates" and have the correct coordinates, they would be able to place a note onto a hidden log that only the user would be able to see. Or, have it that the user would be able to update the coordinates with the correct ones that again, would only be visable by the user when logged into thier account.
Thank you,
Paul (Zef *)
