This really is a great tool (again, I'm not the actual author, so don't take this as bragging), but I'm only doing VERY limited maintenance work (I'm only keeping it alive based on patches received from tech-savvy users -- that's merely bureaucratic work). Instead, I am actively trying to match ViewMyCurrency's excellent currency conversion features in my own Converter extension (a link is available in the column to the right). As of version 0.9.0, the Converter still lags behind ConvertMyCurrency in regards to currency conversions, but you might want to check it out nevertheless.
