As tricky as it is not to feel patronised, I will accept that there were one or two
forum-related things that I needed to learn. Emerald Tiger thanks for the detailed instruction, but I think I have the card-design part down. Thank you for pointing out one useful detail about the "Idea" row though, which I now know is for "to whom do you credit the idea behind this card?". So, thanks, but also, muh.
Now if anyone would care to talk about the card itself...
