Sorry guys, I guess the confusion was really caused by me. I did indeed first post it in the Lufthansa forum and then CGK suggested to post it in the Star Alliance forum which I subsequently did because I felt (and kind of still do) that it would be more appropriate there.

I understand, however, that moderation is necessary to keep the boards clean and organized and I am thankful that Patron takes the time to do that (moreover, he also gave me some really good advice, thanks for that as well). As to the "strictness" of policing, I guess it is up to the individual moderator's judgment.

I was surprised that my thread was locked because from other message boards, I am used to threads only being locked when they are really redundant or offensive. I assumed that not all people read both the Lufthansa and the Star board.

Back to my original question - if I understood all the answers correctly - EVEN IF I have a Business class RTW ticket (whether it is an award ticket or not) - if I want to change the date of the flight, I have to pay. So the only difference of the business class ticket to the economy ticket is that I sit somewhere else and get more miles (if I pay the ticket)? I am not sure if I would want to pay more than twice as much for that .
