Thank you for the information!
Everything is very confusing in the beginning so it is very useful for me with tips from others how to do. Thanks!

I've been mining for awhile now and ready to start spending.  I've been looking for a good "how-to" on signing and this is very helpful.  Thanks.

Hi,

I tried to follow the steps just for kicks,
and inserted a transaction I made a few days ago in https://blockchain.info/ :



For some reason I get 2 addresses listed in the "Sending" section (they are both mine)
and on the receiving side there is the address I sent the BTC to (the first one) with the amount I sent
and another that I don't recognize with an amount I did not send.

What does this mean?
from which address did I send the payment?
