Tailwind is incredibly helpful and the Firefox extension saves a lot of time. It's awesome being able to schedule repins from Pinterest, schedule pins across the web and discover new content for my boards. The new Board Lists feature is really neat: you can save groups of boards together and then schedule a pin to multiple boards at once just by selecting the board list, instead of having to duplicate the pin for each board, one at a time.
Tailwind has saved me countless hours. I can schedule all of my pins for the week in one sitting. Best of all, Tailwind knows when my followers are most active on Pinterest, so I know exactly when to schedule my pins so they post at the best possible times.
