I cant figure it out. I want to be able to help those behind me..
you buy an item from a shop i believe that allows you to write/rate/view messages, red soapstone maybe, the white soapstone is what you place down for other people to summon you.
Orange soapstone. Costs 100 souls at the vendor you meet in the Undead Burg.
Is there other merchants later i can buy it from?
No doubt...it's a common game mechanic, so they will make it available as much as possible.
is the fat*ss the one who sells it
