I love the fact that you keep trying to define your own vocubulary 'Deck' etc, but always have to explain it. Best to stick with the more eaily understood term, rather than invent your own, I think. Unless you're going to try and trademark them all.
Thanks - we discussed that a lot - we were trying to make a simple 3 steps process. If we get a lot of feedback that it's confusing we'll ditch it.
I hope that saves you some time.
