I remember that around the start of service, there was a motion to have people write their gaf handle in the search comment box (that shows up as a speech bubble on player lists) in the game, but not that many people seem to have done so.
I believe that was me, but the notion was immediately shot down when I was reminded that you can't choose your opponents.
And, I really should've appended that quote from the Reinheart translator guy with a "lol", because it really does stretch belief that YoshiP would expect all 512 members of an FC (hypothetical, I don't think many are >100 members) to farm for weeks and then donate 100% of the money they've earned since lvl 1 to housing. It's like a blatant RMT baiting exercise.
