Hello,

I just started playing ClassiCube but i don't know how signs block works.

Can someone help me please ?

Sign blocks, otherwise known as Message Blocks, are blocks containing a message in them that appears in chat, to see the message, you must hit or right click the block to display the message.

 

If you want to make your own sign block, go in chat and type in /mb [block; default is white] [message], however servers changes the permissions of the command, so you may have ask anyone who has the permission to place a message block to place it with your message that you said to them.

Blocks like that might work differently on each server, so it's useful to tell which one you're on.
