Open a better world wiki. Everybody can contribute. An idea from Bart

we can gather information on the best things to do and buy to make your own world a bit better.
Tips: nothing is what it seems: is some green energy supplier not providing real green energy: put the information in the wiki. Anybody looking to select an energy supplier can first look here.
Actions: who is organizing actions and how can you help?
And 1000's of other things might find a place (you don't have to think of everything, because everybody helps you).
