Note that the "by Michael Parker" and similar footnotes are because the article originally comes from a blog post on Decipher's website. There's no need to sign off every edit, and if the article is added to or substantially changed we can always remove the attribution, since it's embedded in the article history.
Still, what a milestone! A small percentage of cards, but I think Dictionary's got the right idea to do this moving forward...."write an article for every card" is a rough goal, but "write an article for all [culture] cards in [set]" is much more doable, apparently.
Congratulations all around for the writing and editing effort!
