"You are a merit source. The next XXX merit you spend will come from your source rather than your sMerit balance. Merit spent from your source will come back in 30 days. Unused source merit is wasted. It is not allowed for merit sources to sell their merit."
I found this quote slightly disturbing - it would tend to imply that others who are not merit sources are allowed to sell their merits. That rather kills the whole concept.
