thx Vrontis and smaragda
OK - but which is my account?
I see 10 accounts on the Account tab - just tried click the New account button and no 11 account popped in the list..
All of them are your addresses.You can have many many address.
Your account actually is your wallet seed which contains numerous addresses.
You can have Qora's in any of the address there.
To add to what Vrontis said, when you initially created a random account, Qora created a "seed", and you should have been prompted to save it. (You did save it, right? Right???)
Ok, that seed is used to derive your payment addresses. Your "seed" is the most important piece of information that you have. I recommend that you save it to a USB flash drive and put the device in a safe place. If you want to buy large amounts of Qora, you may want to also copy the seed into a document, print it out and then put the document in a lock box, for safe keeping. It never hurts to have a redundant form of offline back up, in case something happens to the USB drive.
All of your addresses derive from your seed. You may not recall but when you launched Qora for the first time, you were prompted for a number of addresses to generate. It defaults to 10, but you could have said 1... 5... even 100. You can receive qora into any of these addresses. Each address is independent of the others, but they are all yours and they can all be recovered from your seed.
Also, for further clarification, your password has no bearing on the generated addresses that came from your seed. So that you wouldn't have to remember your seed (or save it in an unsafe text file on your PC or, God forbid, Dropbox) Your password is used to hash and hide your seed. If delete all of your local data, you can restore your wallet by entering your original seed. When Qora prompts you for a password, you can change it to what ever you want and you will still be able to recover your finances.
