How about an all Server Message when an FC buys/builds a house? We really need something to bring people's attention to housing in general and with prices the way they are a server message would not be spammy. House purchases on Gilgamesh have been in the range of 2-3 a week at the highest.

I am not sure about the "board outside so people can write comments on the house" but a little more information on the house on the placard would be nice. At the very least please add "Established: <Date>" on the placard.
