Adding Ajax to userspice

[rahadi]

Thanks Brandin. Somehow find a solution, but still I have another issue. I already have a project with the following directory structure:
Myproject
----->js
----->css
----->core
----->includes
----->index.php

and now I want to add userspice as a module to this structure which should look like this:
Myproject
----->js
----->css
----->core
----->includes
-----> userspice
-----> index.php

Now, how to manage my private and public pages by userspice as the z_us_root.php file is inside the userspice directory?
thanks
