ha - try using irony. For every Brit that likes a good whinge, there's an American that thinks that irony is a State in the Middle East.
This post by our dear Jimbo got me thinking for a change (that doesn't happen often). If the national flag appeared on the left side next to a username it might help the Amis to know when we Brits are deliberately winding people up, and for us Brits to well, ignore 'em! Thing is there are of course Amis who get our jokes, so can add to it too. Of course all those "agony aunt" stalker-type "I met a girl at Oktoberfest..." threads should have a Swedish flag on them, imho.....
