When an author says "Thank you for reviewing", what is left to be said?
I agree 100%. Thank you for your 'thank you' would be just too ridiculous. Although, can you believe this, I had a "thank you for your thank you card' sent to me from a Japanese friend once. I was just so damned tempted to send a 'thank you for your thank, thank you card' back, just to see if he had to have the last 'thank you', but I never did.

Oh, and Curtis, I thought you were a female. Well that's ok because you thought I was a male, didn't you? So I guess we're even now.
