P&P is putting together guidance for WCF security and is looking for feedback from the community. Now is the time to influence the results from your own practical experience so get in there and review the whole thing or the areas of your greatest interest over the next few weeks! The feedback will be really useful!

J.D. Meier's blog has a link here:
