I have tried to categorize my collection of URLs. Naturally my way of grouping things won't correspond to everybody's opinion. So no flames about this please. BTW, this page is totally ugly but it's useful and that's the point :-)
Besides that, I have to stress that I didn't test all the addresses in this
list. There might be lots that are outdated. Please tell me
if you find anything that should be taken out of the list, whether it's
gone off the net or simply bad.
Say NO, now that you still can.
