Sometimes it is very helpful to save a freshly created MOSS site as a template to install it later on another platform. Once uploaded to site templates library, you may still miss the templates in the list of custom site templates.
Why? Because the template language differs from site collection language.
What to do? Change template language to be same as site collection language.
How? Use manual instructions (currently in german, but you may try to translate in in english online )
use a freeware tool .STP language converter
