Also, 250 BTC was probably lost when treasurer paraipan died, unfortunately. Recovering that BTC is maybe still possible, but it's probably unlikely.
The forum currently has about 5568 BTC in reserve.
Have you considered offering a bounty of 5-10% of the total amount for anyone that helps in recovering the 250 BTC? I had the impression that paraipan was a semi-public figure in the Bitcoin world -- or at least in Spain, so maybe there are some Spaniards that got to know him well enough to know how to reach out to his family.
