I do wish I had heard about this before, and not just because of the the giveaway.  Read my post in JR's MasterCoin announcement post why I really do believe that this concept is truly great:   https://bitcointalk.org/index.php?topic=265488.msg3043032#msg3043032   Here's my bitcoin address where I can send and receive coins.  16QVMPtTetYobyKnzrM2mnkuy6dfmMmYG5

I also wish I had more time to buy into the MasterCoin project, but I just don't have the time today or before the end of the month to officially qualify.
