The currency converter doesn't include the Russian Ruble. I understand if they can't include every country, but Russia is probably more important than many that are included.

What has happened here? A great piece of software that was extremely useful, quick and easy to use, especially for currency conversions seems to have bitten the dust (my currency conversions no longer work!). As the last reviewer points out, the web site seems to have completely vanished off the planet. SHAME!
