There should be an option in the Client Area to choose a prefered currency, this way we'd see how much things cost in our native currency instead of just Euro. I imagine it wouldn't be too difficult, you could use something like https://openexchangerates.org/ to get the up-to-date currency conversion rates in JSON and have Javascript do the rest. It's not a huge deal, but it would be a pretty cool feature, and make it easier for members.
