As an Auld 1950s Edinburgh Man originally ( and for our American friends and cousins, it's said Edinburruh not Embro or Edinboro! ) I had to ask Mr Google what irrc meant, but as they say everyday is a learning day!
I always thought it was an American Forum, given how most folk here seem to hale from the USA and anytime I've paid in money to it I had to pay in USD.
So far in all these years I've not met anyone here who owned up to coming from Scottish Scotland ( which by the way is NOT part of England ) ... and we're really no that bad!
