Sorting - if you are going to make use of this site for your colleccting, then sort by Year, Company, Set, Card # as that is the order they will be displayed in be it for you rplayer collecction or for set building.
For getting a card added, if the set is already in the database, you can submit an IR by going to the set's page and finding the link of "See any Inaccuracies".
If the set does not exist, you can upload an image in the Mystery Card Forum post and ask if anyone knows if thie card is in the database. But before you do that, do a thorough searc; easiest way for a ports figure is to search the name of the person adn then use the filters to reduce to just the cards that have the number of the card you wish to identify.
