Torsten just finished creating a German version of RSS Bandit. This should make it into the next release which should please our various German users. As Torsten mentioned we are looking for volunteers to do other languages. We will need at least two volunteers per language so that there can be some degree of error checking and the like.
To get started with translating RSS Bandit, only one file a number of files need translating and these include RSSBanditText.resx, the resource files for the main GUI, and the resource files for the various dialog boxes. An example of a translated version of that document is Torsten's German translation; RSSBanditText.de.resx.
