hi bernd,

thanks a lot for your help! it seems the whole thing isn´t that easy!
Or in other words really a bad idea! Do you know if it´s possible to 
build a new extension based on an existing with the extension 
kickstarter? i never used it before.

maybe its much easier to take a similar extension like nicosdirectory 
and change this for my needs. (the third way extending nicosdirectory 
for two funktionalities seems to be very hard, and a lot of php 
programming).

thanks a lot for your help + happy new year!
