I'm setting up a site for a small NGO with an impressive 35 year history. Instead of just dryly listing all their meetings, publications etc we have decided to also add some of the political and environmental events that shaped those decades; events that on the one hand set the scene in which they were active, and events on which they had input, and admittedly who remembers from the top of their head in which year the Chernobyl disaster took place, when Austria had a referendum about nuclear power stations, or when mad cow disease was first diagnosed?
