 I'm glad I could contribute something other than annoyance ) To be honest I had no idea where to look for the discussions, I scanned around the PW pages but ""readily available"" might be pushing it ;) Going back a few pages I did see a few discussions in the archive covering the same ground I've brought up that also referred to even older debates but I couldn't check back further to find them still. I recognise wiki is a labour of love and none of us have unlimited time to spend on this, but if possible I think the project would benefit if someone could collect together big important discussions like that when something's been decided, so they can be easily linked to for reference and to shut guys like me up with one click (it's always interesting reading over debates and it keeps me quiet for a while). Also it might benefit the reviewal of policy so it doesn't become something of habit set in stone beyond question, if it's something easily accessible that can be looked over freshly with all the factors to hand. Don't mean to be complaining or telling any of you you've been doing a bad job though, blah. Likewise I didn't mean to be kicking up a stink I'm just a stickler for seeing proofs with my own eyes and seeing for myself their interpretations, as is probably obvious now. This isn't a bad article by any means. 
 ANYWAY yeah no rush I'm sure you'll do a great job on the article, I trust you on that so don't feel like I'm looking over your shoulder on this.   "
