The Cognitive Sciences proposal on Area 51 is almost launched. I've committed myself and we could use just a couple more subject matter experts or people with many, relevant questions to the greater field.
Since the Cognitive Sciences, especially Cognitive Psychology and Cognitive Ergonomics are extremely important to HCI and UX I thought some other users might be interested/proficient enough to join.
Don't join if you don't have questions/answers/a good knowledge of the subject due to the limit number of seats. If anyone has questions they would like posed on Cognitive Science.SE in it's private beta I would be more than happy to ask on your behalf.
