Ok, one call them saves. i just think it sounds stupid. Srry. To make a link, Put a bracket "{" then c:(save id|What you want to be shown in the sign) and then a end bracket "}". All together it looks like {c:989213|Pie} Replace the numbers with the save id and the Pie with the words you want in the box.

I think he put it in two languages although he can just put the translation in this one. Most people on here speak English though so I dont understand why he would do that.
