I have a simple question:

This plugins Readme says:

Prerequisites

This plugin requires the following Zen Cart environment to successfully run:

Zen Cart (v1.5.1 or later) installed and operable.
phpBB (v3.0.11 or later) installed and operable in a subdirectory of the Zen Cart installation.
The Zen Cart®/Bulletin Board Integration via Notifier Hooks plugin installed in the Zen Cart installation.

I have tested it and it works great this way, however the live website should have

* The PHPBB Forum in the domain root (being the main site)
* Zencart 1.5.3 in a subfolder (being the shopping cart where users pay for some type of subscriptions)

Is this possible with this plugin and which modifications need to be done?
