A WebmasterWorld thread reports that Google AdWords has added a feature for non-U.S. based advertiers. It is called the "currency indicator" and it shows what currency you are being billed in.
Advertisers who are in Canada see a CAN near their numbers, while advertisers in Australia see an A near their currencies.
One member described his difficulty with this new user interface:
I'm not sure if this is only an international thing, but as of today the Adwords UI now shows "Can" in front of all figures that have money in them. AWA: This makes cutting and pasting and reading the UI REALLY HARD NOW. Please ask them if they can put it up at the top of the window as a permanent setting or something, it doesn't need to be stuck in front of all the dollar figures. Please pass this feedback along!
There are several complaints already in the forums.
