Writing Floor Messages
In Dark Souls you are able to see messages from other players scrawled on the floor of the game world. You can also write these yourself. They appear with a different image next to them depending on how other players have rated them.
To rate a message or write one of your own, you need Orange Soapstone. You can buy this from the merchant in Undead Burg. You can use it whenever you like and it will not be consumed. Select 'Use Item' and you will be able to write a message. Select it while standing over another message, and you'll have the option to 'Rate Message'.
