1. I've added further detail to my last post. The whole point of a brainwallet is so you dont have to worry about saving the wallet.dat file so lets move on.

2. When the wallet was created there was no reason not to use the brainwallet method.

3. Appears the orginal paperwallet & brainwallet websites that may have been used are no longer active.

4. My understanding is there were only 4 orginal wallet genteration sites with the other two being warpwallet & bitaddress.org.
