If I understand what you're saying correctly, you don't. The users for
site management and the site users are drawn from the same pool.
Generally, you assign the users you want to admin the site to the 'site
admin' group -- most admin actions are already setup so that members of
this group have appropriate permission.

It sounds like you want to modify the boxes displayed by URL. Or do you
want the full template to change based on URL?

Generally, your app is in one or more packages. For instance, I'm
developing a contact database -- people, phone numbers, addresses, email
addresses, etc -- in the package 'contact'. In that package I have a
file (conf/action.perl) that maps top-level URLs to code, something
like:

$action = {
   person => {
      class => 'OpenInteract::Handler::Person',
      method => 'handler',
   },
};
 
In that package I create a module 'OpenInteract::Handler::Person' which
inherits from either 'OpenInteract::Handler::GenericDispatcher' or
'OpenInteract::CommonHandler' (more high-level stuff). These packages
look at the URL and dispatch the request to the appropriate subroutine.
So:

  http://mysite/Person/show/

Generally gets sent to OpenInteract::Handler::Person->show()

From there you have access to the OI environment (user, theme, session,
security, templating) from which you generate content.

It's probably easiest to look at an example. Take a look at the
'classified' package that's shipped with OI.

Good luck!
