I'm working on a website which has multiple admins, some creating contents, some editing and some tagging...

I know editing one node at the same time will cause this error, is there anything else cause this error?

Question: Would it be a problem if all Amazon links were converted to affiliate links?
Answer: (Two different respondents said:)


  Amazon affiliate links should be a
  bannable offense. 
  
  I'd post any
  user-generated Amazon referrer link as
  offensive.


Ok, WHY?  

If a person follows the link and buys a book, something is going to happen to the affiliate fee. Either it goes to a SO member, or Amazon keeps it.   

Why is it so vitally important that Amazon keeps it?  Are you stockholders?
