This may be a really ignorant question, but I haven't played in a few months, and just now joined an FC that has a house; but how much is the cost of a private room?

Also, I agree with the knock system. Very much like the OP, I'm I'm going to decorate and set up the room the way I'd like, I'd rather not EVERYONE in the FC's over 200 members be able to just stroll in haha.
