Yes that is so

You make tha page and insert the following script at the top before the <html> or any other PHP you might have.
if ($url == false OR $zone == false OR $zonegroup == false OR $usergroup == false OR $admingroup == false) {
header ('Location: http://www.yoursite.com/forum/index.php');
exit;
}
to send users to these pages first you have to enable the system in the forum settings which can be done from admin.
The you insert a zone number as such into the Edit Zone Members page in the admin options menu located below Edit Member Groups, there you specify the zone number and the address for it to go to. The address will be as such .
/login/zone1/zone.php
it starts at your websites root directory as security is implemented via includes and checking to see if variables exist and so on, security revision being done for next version.
Yes you have to put the link on a page or modify the forum to have a button im doing so currently for the next version.
But to send a user to a zone you have to put in their zone number as you set for their membergroup another one being revised. I didn't release it as a Beta because its not its fully functional just not as advanced.
so link to the zone is
index.php?zone=zonenum
they are only able to goto their zone number if the one in browser is changed it is like calling a different zone so they are rejected.
to link between pages in a zone use this format
index.php?zone=zonenum&link=/zones/zone1/page2.php
once again starting at your default directory.
I recommend wait for version 1.1 which should be out within a week or so major userbility (you included) and security/bug fixes.
Ahh yes and the example goto my Clan site and sign up i will give you access using the zones system to my members area to show you what i mean
