Once a sign is removed it becomes a sign block, which can no longer stand upon the ground as a sign (it basically loses the stick that supports the sign), and can only be placed flat upon another block.
New lines can be added by using _ in the edit.
A sign's texture can be customised by prospecting (Y) and pressing A.
- If the block is removed while a wood sign is placed on it, the wood sign would not be removed.
- Unlike it's Minecraft counterpart that doesn't allow cussing in it's signs, totalminer forge players can freely type cussing into their signs without having it censored.
