I can understand your frustration, but the verification code is used on many sites. It helps to stop bots from making accounts. It is a useful hassle.
I find if I don't take my eyes off the code, not even to look at my fingers, but focus very hard, you can see the letters.
Unlike Rewind, you don't have to enter the verification code every time you post. That in itself is wonderful. Once in here, and verified, you're set to go.
