怎樣刪除Gmail 帳戶？

How do I cancel my Gmail account?
If you decide that you don't need your Gmail account anymore, and you're sure you won't want your username in the future, you can simply close the account. Here's how:

Click Settings at the top of any Gmail page.
Open the Accounts tab.
Click Google Account settings.
Click Edit next to My services on the right side.
Click Delete Gmail Service. Once you close your Gmail account, you can't reactivate it, and you won't be able to retrieve any messages.
