Everyone spends time figuring out the best way to do things
One of your most valuable resources is this Forum. The collective brings together knowledge from a mind boggling range of experiences and places with an equally diverse range of products and surfaces. And the wonderful thing is, that everyone is willing to share.
I hope your new job is a blast!
