Hi, I was confused about some of this, it kinda put me off slightly tbh as it seems pretty confusing because the client I'm using (bitcoin-qt, which I think is the Satoshi client?) Doesn't really give much info over how aged particular bitcoins are, or even which address has which amount etc...

Is there another wallet program which can use my wallet.dat to give me demo figures, and how do I send transactions without fees as it won't let me, even though I set it to 0 and I tried that addnode thing from the wiki.
