UPDATE #3:
We don't allow any anonymous entries anymore. All existing entries must be linked to a BitcoinTalk Account, or the investment will be forfeit. Deadline is May 10th 23:59 UTC.
So how is this going to work exactly? Are you going to match up password hashes of those that bought into categories #2,3 & 4 with the password hashes from the "Free Giveaway" category?
Or do you want everyone to PM you and "claim" which investments are supposedly theirs? (How can you tell if they are telling the truth?)
