I have no spam filter going and could not join the forum despite three attempts. I received emails back stating they couldn't read the serial number in my receipt.
I didn't need to find an answer to anything in particular, but thought I might pick up a tip or two. I haven't tried recently.
I suggest reading the manual from one end to the other. It will answer many, many questions and will bring you up to speed quickly.
Also read Michael's review as he outlines the basics of it's capabilities. Very good reading.
Also, Bruce was active in a thread in the forum on this site recently concerning sharpening on layers.
