Sarah is quite right. This is a public forum and she is within her rights to reply on it. Also as it is a public forum putting your phone number for all to see is maybe not the best thing to do. There are some dodgy people out there that might 'have fun' with it.
I would suggest if you wish to pass your number onto people then please do so in the form of a private message. Not only does the person you want have your name and number, I do, Sarah does and anyone that has a computer has access to it.
