Help on this Web site
Links to "external" pages, i.e. pages outside the VTF Website, are marked by a following arrow (). In order to make clear that external pages are not part of the VTF Website, they will be opened in a new browser window. Links to pages in foreign language are marked accordingly (for example for an offer in French language, or for pages in German language which haven't yet been translated into English).
Many thanks to Thomas Wingert (Chicago, USA) and Jutta Liebmann (Bielefeld, Germany) for their assistance in translating the VTF Website.
