Hi Professor,
One of the current testers suggested the following and I told them that I would pass it on to you.
Maybe a forum section for only the testers could be good idea, and only we could see it (I’m sure the forum software CAP uses could handle this) and there could go the instructions and when someone doesn’t understand something then you could answer it. It might be easier than keeping record of 16 people, and what they are doing. But it’s just a suggestion, I saw the Prof’s team are working on some automated thingy.
