Yeah, noticed that. I also just saw the yugioh-reddit has links to three Yu-Gi-Oh forums in the side-bar, but those include the Pojo forum, and two other forums which are almost equality as inactive: YGOrganization and DuelistGroundz.
Ah well. I guess I’ll just post my upcoming article on reddit with picture-links, as well as here by modifying my earlier created Rarity Collection post.
I’m done with compiling the list of Yu-Gi-Oh rarities since yesterday, although I still have to wait for loads of them to arrive since I ordered new cards the last couple of days. Right now my list contains 108 officially released rarities (although I’m unsure about 3, which were the only ones I was unable to find/buy thus far), as well as 69 misprinted rarities (although I’m still missing quite a few of these, and I’m sure there are more variations to be found). Might still be a couple of months until the article will be finished and posted, but I doubt anyone knew there are more than 150 different rarities for Yu-Gi-Oh. 
Greetz,
