Minecraft forum status icons
By popular demand: a set of Minecraft forum status icons. These are straight out of the game and licensed under a Creative Commons Attribution-NonCommercial 3.0 license. You can thank Notch and the Minecraft Wiki for it; all I did was resize them.
The unread forum icon is a diamond block, the read forum icon is an iron block. They're 36 x 40 px transparent pngs.
Note: be sure to make the appropriate changes in the Node Icon style property (Forum List group). Under miscellaneous, the height should be 40px, not the default 36. Width is fine on 36.
