Hi Dieter and others, first of all: thanks for your great product: i admit - it looks like the perfect choice to me. I installed it on Zope 2.3.2 and get the following behaviour: My structure: root |- german (has its standard_html_header) | `- research `- english (has its standard_html_header `- research `- ProjectOne (folder with index_html: <dtml-var standard_html_header>Welcome.<dtml-var standard_html_footer>) I installed a MFolder as "root" (see above) with a MirrowId__ set to "english". When I type in the following URL into the browser: http://server/root/german/research/ProjectOne I get the english standard_html_header along with ProjectOne's index_html. Is there a way to modify your great product so that ProjectOne's index_html <dtml-var standard_html_header/footer> get the german's standard_html_header/footer? Thanks in advance for your help, Philipp Robbel
