I am a bit puzzled by the behaviour of this wiki. I think it should be like on Wikipedia where there is a separate page for discussion about editing, so that conversation between contributors does not clutter the article page. Unfortunately, the tabs above do not seem to work like that (do not seem to do anything at all). I will look into this when I have the time. But as I told some of you, I need to travel to the Netherlands this week – no lab on Thursday, no chat tomorrow. I will relax the deadlines. But I want you to choose your projects. /Pieter
