not that I am a power that be anymore but I am going to tell you the reason.
( also like Russ says your name pops up in face book, and also this thread here has popped up too since you entered your full name.)
The reason it has found it is because google is a search engine and since you submitted your name to chordie, google has picked up on this and displayed it. Just the same as it has with every other site you enter your full name in.
If you do not like this then I suggest you do not enter your full name online anywhere unless you know you dont mind.
I dont see what the problem is. It is only a name. It is not as if all your bank details etc is on display, and certainly not from chordie as it does not ask you for any of those details.
I think if I googled my name I think it might show quite a few sites.
