Another administrative point:
I also don’t like, that when you click on introduction, you see two articles, both minimized. At least this text should be open or the “About this page” article should be hidden. Not sure how to achieve this here, but is is just one more place, where a visitor has to click in the proper place the find the info she expected. I’m quite sure I don’t have to explain to you Björn 
Probably not much we can about it. At least I did not find anything in the settings. Unless someone want to hack discourse…
