Hi, the thread you refer to is about how to upload your card lists, that is, your haves and wants, not the list of cards making up a game.
There are in fact no instructions yet for uploading a new game to the site, so I'll explain it here:
You need to gather the complete list of cards for all the existing expansions of the game, and format them in a similar way as it is required for new sets in existing games. You can see instructions for this on any game that does not have a Herald: just go to
"search for a card", choose a game (for example,
Vs. System), and click on the link that reads
"Upload data for a new expansion set"
The exact data you need to provide for each card varies depending on the game you are trying to upload, but you always need to include the card name, number, rarity, and type. The next most important field would be the game text.
As the game is new and there is no section for it yet, you can't upload the new sets directly through the site, so you will need to send the text files to us by email. Just use the linke
"Contact us here" that you find at the bottom of every page on our site.
Please let us know if there are any questions about this.
