I have submitted the request. Normally I'd tell have you do it but this card being added is something I need to be done for another project. So thanks for pointing out this release because it is something I missed when researching the Digimon games that came with cards.
But in the future you can Browse to the type (Gaming, non-sport, etc) then click a year and then Click Add Set button to get to the form for adding a missing set. Just make sure to remember that if you are adding a card that exclusively came with something (such as a video game) you use that product's release year and not the release year for the set the card is a part of. Such as in this case, while the Digimon D-Tector CCG card sets were released in 2002 (they are in the 2002 section of this site), the Game Boy Advance game that this card came in released in Jan of 2003, so I had submitted this promo card as a 2003 card.
