Well to share just got to your chest/closet and at the bottom of the screen you see press select ( i believe that's the button ) for near. Once you pick the item you want to post it will open the near app and post it.
Now if you are looking to receive then you need to go to near and click the little bottom on the top right and it'll show you want you psn friends have posted.
Hope that helps Runa also if you ever need help in the game let me know :D
