Strike To Stun has always been and continues to be the nexus of the Warhammer Fantasy Roleplay community. It's distinct in that the website's focus is not on any specific edition, but instead about the Warhammer world as a whole. Heck, the Server Goddess was even kind enough to include the ZWEIHÄNDER Grim & Perilous RPG official forums!
Visit the STRIKE TO STUN website, and never look back. I guarantee you're bound to find something that will inspire your own WFRP 3e homebrew material! Because we all know that it's now up to us to steward the product, as Fantasy Flight Games remains uncommunicative with its fanbase.
