[Plugin: WP phpBB Bridge] How users are handled.

I have a quick question about how users are dealt with, I used to use a phpbb bridge for my old cms, and this one seems to work in the same way, however the later synced the users on both platforms.

I thought this would do the same, I have an existing phpbb3 install , so when I setup the bridge I was expecting to login to WP Admin and see a ton of users in its user list, but I still only see the two that were there before.

The Bridge is working, widgets all working just wondering about the users.
