Another FYI for the thread, because I got a little confused on this last night...if you are trying to manually verify a transaction, and you are looking to make sure the person actually has the mastercoins, the last accepted block that counted towards the initial giveaway was block 255365. I got a little confused on this because the white paper says before August 31st, but the person may have legitimately sent BTCs to the Exodus address on August 31st as that block was received just after midnight in the wee hours of 09/01.
