why do you make an issue of this all of a sudden now?
Seems you were quite content until you found out that someone had offered to donate 10 Euro per month extra to have a golden rook.
This is substantially more than a couple of prize tourneys here and there.

It leads one to ask, why did you run prize tourneys in the first place? what was your goal?

I currently have one running with 2 6 month rook memberships and I have already paid the cost of the memberships to Fencer. You dont see me getting all flstered about this do you?
