When you search the ships manifest you can know if reached the end of your search. With google you have endless searches and may still never know if you can find what you are looking for.

As an example, if the treasure hunt you are searching for is the Karaoke Challenge Game, if you set the location to country you will see everyone in the entire country that will volunteer for the Karaoke Challenge Game.  Narrow your search to the state you are in.  If you still find people narrow it to your city.  If you still find people narrow it to venue.  If you still find people narrow the time to just today. Now you can apply filters to  find the exact person you are looking for.

Activity, Time & place and are combined with filters when searching the ships manifest. 

Example #1

In the city of Helen, during Octoberfest, you want your team to compete in the "Chicken Polka Dance."  You will create your own contest at the hotel where you are staying.

Solution

Post this on the bulletin board.

Activity - Karaoke Challenge Game - Chicken Dance, British surrender the booty 

Time 8 pm Saturday

Place Hotel pool  (When you post on the bulletin board, the venue name, city, state and country is automatically included and mapped for you.)

Example #2

In a couple of weeks you want to have a darts tournament, pot luck BBQ & pool party at your apartment pool.  You just moved in, you don't know anybody.

Solution

You can show a QR code on your phone to people you meet or print a flyer with the QR code.  This will register you as their President and the HOA clubhouse as their "Birthplace."  Anyone can post activities on the bulletin board.  If you grow this group and start competing with other HOA's by creating QR codes and flyers for them, you might eventually have a lot of citizens and collect lots of Federal Taxes!  (The 10% referral commission you get when somebody donates is called "Federal Taxes.")
