Its really simple so let me explain. First off to add parks or rides, you must click on the top link titled "Ride and Park DB", then fill the search table with the parks name. Once you do that, you will be guided to an area with information relating to that park, just scroll down and you will see a list of rides and rollercoasters. Nextly, just check the boxes next to the rides you have been on, then click "update ride count" to have those rides added to your account. Also, when you add a ride it will automatically add the park associated with that ride. So hope that helps.
