The helferlein_Business skin was designed by me for this site. It contains two skins (Portal with the menu on the left, and Admin with the menu on the top and no RightPane) and four containers (Standard and Standard - No Title for the ContentPane, and SidePanes and SidePanes - NoTitle for the LeftPane and the RightPane).
(This is the "standard" helferlein_Business Skin. In the meantime I created a localizable version, helferlein_Business.ML, which is not available for download)
