I don't really understand the fixation with "the rules"- it's not stalinist russia here (or, at least, shouldn't be!).
Just had a quick skim of the two reviews OP posted yesterday. Yes, some further info would make the reviews more helpful, esp price and services, and probably would not take much more time.
But, on the other hand, are we better off with those reviews, or with nothing? Overwhelmingly the former, I'd say.
So why discourage people from posting?
