We present the key results from an intensive and coordinated ten-year amateur observational programme designed to uncover and confirm Galactic planetary nebulae (PNe). This was undertaken and led by a dedicated group of largely French amateur astronomers in collaboration with professional colleagues. Over this period this group has uncovered a total of 209 spectroscopically confirmed True, Likely, and Possible Galactic PNe, with the work accelerating over the last three years in particular. These new discoveries represent ~5% of all 3831 True, Likely, and Possible Galactic PNe currently known according to the HASH database as of March 2022. A further 610 PNe candidates are awaiting follow-up. These figures demonstrate the power and value of the amateur community in undertaking a coordinated and focused programme such as this.
