Signs can be written and come in two variants: Wall sign and sign on a sign post. Signs can be placed on the top and the sides of other blocks, but not below them.=告示牌可以书写内容，并且有两种样式：墙式告示牌和立在告示牌柱上的告示牌。告示牌可放置在其他方块的顶部和侧面，但不能放置在其下方。
After placing the sign, you can write something on it. You have 4 lines of text with up to 15 characters for each line; anything beyond these limits is lost. Not all characters are supported. The text can not be changed once it has been written; you have to break and place the sign again. Can be colored and made to glow.=放置告示牌后，你可以在上面书写内容。每行最多可写15个字符，共4行文本；超出这些限制的内容将丢失。并非所有字符都受支持。文本一旦书写完成就无法更改；你必须破坏后重新放置告示牌才行。告示牌可以被染色并使其发光。
