Within the next 5-7 years my career will be over and finally, I will retire up north to my cottage where I expect, for the first time in my life, to do absolutely nothing - if I can pull that off. As I look back over 30+ years in this business I think the greatest gems of advice I have gotten were from dedicated mentors - far more so than say my postgraduate degree or any 'formal' education - and a good mentor's advice extends way beyond merely answering a simple question as it can set the course for a mentee to learn how to answer their own questions.
I think what you and Andy are doing is simply great. I am a little confused because your mentoring web says that you are taking only SQL professionals - so I hope you realize that true mentoring has less to do with a given product, than it does with the person involved, but I still think you've got a great idea going there and I wish you success with it.
Well done gentlemen! A great idea, and I hope it takes off for you!
There's no such thing as dumb questions, only poorly thought-out answers...
