Absolutely my point. Nobody is speaking of a "rule" or a "statute" lol or something of that sort! It is just the case, that most of the people who post here are from the UK, there are exceptions, spread across other countries, but yes, UK definitely has the most number of people...wow! this is becoming a debate quite different to what Narmada wrote this post for.
As an instance, run a search for the term 'supervisor' and run a separate search for 'advisor' and see the difference...
