I was glancing at the 2-Page Play Aid (http://www.ramshead.indie-rpgs.com/Files/BarclayUniversalisPlayAidv21.doc) on the Resources page, and happened to notice, under its list of things you could do at any time, it says that dialog is free.
I found this rather odd given that that's a Rule Gimmick rather than a Core Rule, and I would think the Play Aid would tend to stress Core Rules.
