Hi! I wonder if it is possible to create applications in php witch can be extended in the way windows apps can be extended by .dlls (e.g. php for windows with its extensions). The only way that came to my mind was to extend my classes, add required template files and than update the db. But this seems rather complicated to me, especially when you want to install more than one module. Is there a common technic to solve this problem? Does anybody know how mambo manages its extensions? Thanks in advance :) Greetings Mirko
