OUTSTANDING. Beats e-fax, Kinko's/Fed Ex, all of them buy incomparable margins! Price, customer support, tech/innovation - all of it! The difference of apples and oranges! Keep up the terrific work! Well done.

VERY GOOD PRODUCT. WISH IT HAD "ADD/SUBTRACT" FUNCTIONS, WHICH WOULD PRECLUDE THE NEED FOR DOING SO MANUALLY AND THEN INSERTING TOTALS/SUBTOTALS MANUALLY.

Like most of the features, I would like it if I could make boundaries and then just fill in the inside of the shape that I make like the old-school paint application.
