Setting up a Bitcoin address as "your" Bitcoin address or "account" is a very bad idea. You should be using a different Bitcoin address for every single transaction. That is, every time you want someone to send you BTC you should generate a brand new, never been used Bitcoin address for them to use to send you BTC and every time you send someone BTC you should ask for a brand new, never been used address to use to send them BTC.
Rather than go into details I will let you know that
someone has just done kind of what you are asking for here:
https://bitcointalk.org/index.php?topic=755051.0I went into a lot more detail in that thread as to why address reuse is a bad idea. All my comments there apply equally well here.
Ok, Ive read some of you posts and I pretty much agree. But still my oppinion didnt change. In this case there must be something like an automatism to change the addresses a little bit: I buy at Amazon it shows me a different address (name) all the time: "AmazonBitcoin4678", "AmazonBitcoin4679" and so on. Still possible to remember, possible to write down or to tell it to someone on the phone.
