Please excuse me if I use the wrong vocab - as I am unfamiliar with this and so will probably explain myself like a foot. Here goes. I am on a Mac and I think I have downloaded the block chain and I now have a window called Bitcoin - Wallet showing Balance: 0.00 BTC and Unconfirmed: 0.00 BTC and Number of transactions: 0.
Now what? 1) I thought I should be getting an address or something that I need to copy and keep safe - and 2) I should create a Password.
I don't want to close the Bitcoin-Wallet window in case I make it disappear for ever .. 3) Should I be getting a little picture of a wallet on my desktop?
