Most of this site was coded myself (with the help of a patient friend) But not all!
The search script used on the future page is by koinuko. See more of her scripts (with handy explanations) here.
The scripts used for the card sorters are also by koinuko, and slightly modified by me.
I used gloomlee's neoTCG code for my collecting page. The full neoTCG code can do much more than just a collecting page, of course, and acts as a complete replacement for eTCG for Neocities users, automating everything from cards to crayons!
