I was originally introduced to bitcoins by teppy and his Dargons Tale casino http://forum.bitcoin.org/index.php?topic=1392.0 while I was playing his other game ATITD.  I ended up winning around 200 bitcoins total from me purchasing 10 then promptly forgot about it until a few months ago on twitter Jason Calcanis was talking about it and I remembered I had it on one of my gaming machines.  Turns out I had left the client cpu mining and had actually found a block in that time frame.  Since then I have setup a couple of GPU mining rigs and have been lurking quietly on the forums.
