Thanks for the rapid reply. 

 But I think I must try this out in the sandbox first. I want to keep most of the article - with its footnotes - intact but want to insert and/or correct certain statements; so the numbering of the footnotes would have to change. Do I understand you correctly that this process automatic for insertions? 

 It's been a heavily charged discussion, with some Swedes (or claiming to be) saying it's heavily biased and nothing good is said about Ivar Kreuger. He certainly was a very interesting man. 

 I would like to contribute but have no desire to get into an "editing war". 

  
 BEFORE I DO ANYTHING ELSE: 

 First of all: I am going to read up at the links you graciously provided and hopefully try things out in the sandbox. 

 Second: I have to reread the definitive book on the man even though I took extensive notes because much in the present page is correct but so much needs to be added and/or changed and I like precision. 

 Please give me some time. Life will go on whatever the entry Ivar Kreuger says at the Wikipedia.
