It is the responsibility of the casino to make sure that everyone hears about their improvements. It is not that clear to me what will happen, sure it is not going to be something that we need to ignore neither, we need to check it time to time, but if someone doesn't know that there were changes in bitsler (and there were some pretty huge ones) then it could be something that would be a bit responsibility of the casino to get it heard by everyone.
That’s of course not happening right now in a big scale, I am not seeing bitsler marketing their website to a level where it is heard by everyone at the same time. So, I would agree that it’s going to take a while before everyone learns about it.
Obviously it's theirs not us or by any other people outside their management. I believe the reason why they change (remove and add some features, games, etc..) is because they want to upgrade, they want to change for the better.
I only don't know if by the time these new changes occur, they already postponed their ongoing campaigns on the forum, if yes then that was a bad move. If they can advertise their old site before in the forum for a long time, then why not when their site is now on its new version? But die hard bitstler fans will always know every changes made on this website because they will visit the site directly or visit their ann thread here.
