If you click Browse, and then select your player's sport, you can choose the name option and find the player. Most players have a page set up for them. You can then click on the year of the card (in the copyright information on the card if nothing else) on the page that pulls up and scroll through until you find one that matches.
It will take a little effort, the amount of effort in direct correlation to the amount of cards the person has recieved, but eventually you will either find the missing card, or have to request the Admin to add the set if it's an oddball, obscure, or very new insert.
Hope that helps!
VERY slow trading due to health problems. Not transferrable so safe to trade with, just moving is painful and can't always access the cards.
