Winds of Chaos is a 'dead' site, in so much that it doesn't seem to have been updated since 2011, and that was only an 'I ain't dead' post, the first since 2009. Nevertheless, the site is still up, and contains a wealth of resources useful for any WFRP player, and perhaps useful to any Warhammer Fantasy Battle player keen to put a put of 'narrative' and bring a bit of setting depth to their campaigns. You know, to make the miniature game the wargame/role-playing game hybrid that was the suggested by WFB1e (and, some time later, Warhammer 40,000: Rogue Trader).
Probably the most useful content on the site is that produced by Dave Graffam - maker of fantastic paper model kits - under the tab 'Encroachment', including a 26 page expanded character creation booklet for WFRP2e. This is perhaps more than you might want, but it tells you something of the quality and depth of the resources. I also think that the WFRP Treasure Generator is a wonderful piece of work, useful in nearly any FRPG that requires a quick system of finding out 'what has it got in its pocketses'. In fact, the WFRP2e folder on my PC contains a sub-folder which I have called 'Dave Graffam's Excellent Resources', and I'm not sure I have any other folder whose title contains a superlative. So that says something.
The comprehensive set of maps of the Old World, by Andreas Blicher (based on work by Alfred Nunez Jr., with Dave Graffam providing some graphic design on the 'parchment' versions), are also a must-have for any WFRP GM.
