It's in the forum rules but wasn't mandatory to sign up until two days ago. It's so we know who can help you easiest since we have a very global membership.
I can actually help you with this. Do you need to netboot or use a CF/SSD/HDD?
Ok. A netboot zero key is $8 plus shipping. If you need a CF key in the future I can help you as well. PM me with your paypal info and I will invoice you.
