Hi Gizmo,
$_REQUEST['ubb'] = "postlist";
It seems the above UBB request line prompts a UBB Access Denied message.
I'm taking a wild guess for the fun of it, I'm guessing a directory needs more permissions (chmod)?
Hmm. I'll dabble around, thanks for the referral to "generating a page outside of the UBB", that's definitely something I was about to get into sooner or later.
