Previously the board only heard appeals from users about content they felt had been unfairly removed - or referrals which came from Facebook itself.
The board has the power to overrule Facebook's original content decisions.
Its 20 members include former Danish Prime Minister Helle Thorning-Schmidt and ex-Guardian editor Alan Rusbridger.
Anyone can submit content to the board for re-review, providing it has been reported to Facebook in the first instance.
