I see that you edited this area, which is a good thing but you have to keep in mind some basic rules while you make your edits. You have to connect every trail/road to the rest of the trail/road network, because having all those nice sidewalks on the map is definitely good looking but quite useless, because the routing services ( http://wiki.openstreetmap.org/wiki/Routing ) won't be able to recognize/use those sidewalks, give that they are disconnected from the rest of the road network.
See here for example http://www.openstreetmap.org/node/4477512488
Here instead you can find a basic guide http://learnosm.org/en/ and here you'll find everything you need to know about the map http://wiki.openstreetmap.org/wiki/Main_Page
Feel free to ask if you need some help, please connect all those sidewalks as soon as you can.
Thanks
