sorry for bad english
There is no 'bitcoin account' whatsoever. Just install one of the
common clients (I personally prefer MultiBit, but most people stick with Bitcoin-Qt which is kinda 'the standard', based on Satoshi's original software) and there you go. You won't have to register anywhere to use bitcoins.
Well, some websites offer online bitcoin wallets, and obviously you'd have to register there to use them, but I wouldn't easily trust large amounts of money with some random site. Especially if it ain't necessary. The less people, companies or websites you have to trust, the better.
If you want to buy bitcoins with uros or dollar$, register with an exchange. I personally prefer intersango.com, great service, fast, trustworthy, easy, and no need to register all sorts of personal details (in fact all you need is just a random email address).
