I got forwarded this website by a number of my American colleagues who know how I relish teasing them about their abuse of (my) the English language. 

There is now a website dedicated to help my American colleagues ‘localise’ themselves with ‘British English’

It’s called the Septic’s Companion (Septic being cockney rhyming slang for Septic Tank = Yank)

Enjoy!
