Quickform Page Controller (not quickform_controller)

I've created a bunch of generic forms that I will be using in different places on my site, for instance the same form that is used in the sign up procedure is also used to modify your user details as well as in the admin control panel for their administration of the user. I created a simple controller to be able to join up differnt forms and pass values along but I'm not very happy with it. Does anyone have any example code, or suggestions of how a simple page controller could be implemented that works well with QF? My forms are all in classes of thier own and inherit the main HTML_Quickform class. If there is a way to make QFC work with my forms that would also be very cool... on simple inspection I couldn't find a way. Ideas are welcome :) Aaron
