I'd posted this as a response in a GT thread, but per suggestions to make this more visible, I'm posting it here as well:
I've added a guide on Google indexing protection and the protection code usage in the FAQ system. Simply enter the search term 'google' in the FAQ to bring up the relevant
instructions. Note that there are other search terms such as 'protection', 'indexing', etc. that will return these instructions as well, but 'google' is probably the most memorable.
Cheers,
