Obviously you didn't read the message. There are trainers available at CS that are not available here at CH as they are made by different authors. CH is not affected in the least by CS. If you don't want to buy anything, DON'T. No one is forcing your hand.
For the record, I've received about 9.2 million emails over the last 7 years saying 'why the hell can't i buy just 1 trainer, why must I be forced to buy a stupid ass membership'. This is for those people. If you're not one of them, again, IGNORE IT. Nothing at CH changes for you or anyone else.
Thanks PW, now I see the clear picture. I totally forgot the view of people who want just only 1 trainer.
