The Earth Simulations Database is a community driven initiative that aims to make sense of the add-ons available to flight simmers. The basic idea is for users to very easily upload information about add-ons they have installed so that other simmers can find them easily. But it is much much more than just that.
Of course this entire idea relies exclusively on the spirit of sharing your knowledge with others so that in turn you will benefit from the information provided by others.
