糟糕，我把你的 sourceforge 用户名弄混了，抱歉。我查找你的用户名时点错了邮件。你现在已经有访问权限了。
你的 FAQ 到目前为止写得不错！
你可以在 bitcoin.sourceforge.net 上创建任何你想创建的内容。做一个能让新用户了解比特币是什么、如何使用以及为什么使用，并且整洁、专业的网站，会有助于让它看起来已经建立起来。bitcoin.org 上的网站是在我向密码学邮件列表介绍设计论文时，以更像教授风格的方式设计的，但我们已经进入下一个阶段了。
你可能应该修改“将它们分配到多个密钥下”这部分。论文这样说，是指让软件来做，而软件确实会这样做。出于隐私原因，软件已经为每笔交易使用不同的密钥，因此钱包中的每一笔钱都已经使用不同的密钥。例外是使用比特币地址时，发送到同一比特币地址的所有资金都使用同一个密钥；如果你想保持匿名，这就是隐私风险。EC-DSA 密钥大小非常强（为未来设计），实际上我们不必担心密钥被破解；但如果真的发生了，优点是，即使有人投入巨大的计算资源，也只能破解一笔交易对应的资金，而不是某个人的整个账户。关于如何备份钱包文件的细节在问答汇编中，也在 readme.txt 中有说明，而且绝对应该放进 FAQ。
哦，我明白了，你是在回应 byronm 在 freedomainradio 上的担忧。我明白你所说的密码功能为什么有用。银行允许任何知道你姓名和账号的人掏空你的账户，而你不可能从尼日利亚把钱拿回来。如果有人在你的电脑上安装键盘记录器，他们同样可以得到你的银行密码并转走账户里的钱。一旦我们给钱包加上密码加密，就能更清楚地说明我们比银行安全得多。我们使用强加密，而银行仍然允许任何知道你账户信息的人从账户中取钱。

Oh crap, I got your sourceforge usernames mixed up, sorry about that. I clicked on the wrong e-mail when I was looking for your username. You now have access.
Your FAQ looks good so far!
You can create whatever you want on bitcoin.sourceforge.net. Something to get new users up to speed on what Bitcoin is and how to use it and why, and clean and professional looking would help make it look well established. The site at bitcoin.org was designed in a more professorial style when I was presenting the design paper on the Cryptography list, but we're moving on from that phase.
You should probably change the part about "distribute them under several keys". When the paper says that it means for the software to do it, and it does. For privacy reasons, the software already uses a different key for every transaction, so every piece of money in your wallet is already on a different key. The exception is when using a bitcoin address, everything sent to the same bitcoin address is on the same key, which is a privacy risk if you're trying to be anonymous. The EC-DSA key size is very strong (sized for the future), we don't practically have to worry about a key getting broken, but if we did there's the advantage that someone expending the massive computing resources would only break one single transaction's worth of money, not someone's whole account. The details about how to backup your wallet files is in the Q&A dump and also it's explained in readme.txt and definitely belongs in the FAQ.
Oh I see, you're trying to address byronm's concern on freedomainradio. I see what you mean about the password feature being useful to address that argument. Banks let anyone who has your name and account number drain your account, and you're not going to get it back from Nigeria. If someone installs a keylogger on your computer, they could just as easily get your bank password and transfer money out of your account. Once we password encrypt the wallet, we'll be able to make a clearer case that we're much more secure than banks. We use strong encryption, while banks still let anyone who has your account info draw money from your account.
