We need to customize the web interface for our client. I am new in iMis, and our version is iMis15.
Seems simply change the master pages under /templates/masterpages/ folder doesn't affect the front-end look. However if I delete public.master, it reports error. If I put an empty public master page there, it still works as before I made the changes.
I notice all pages are inherited from Asi.Bae.Web.xxxx, does that mean we don't have any easy ways to modify the interface?

We are on iMis15 and need to be able to have “new members” join through the web. Once the non-member pays membership fees then be able to register to our conference as members. Has anyone done that ?
