Yes, I solved the problem by just using PunBB's membership system. However, the /config.php took over all of my <forms> (it gives me that cancel/confirm dialogue screen). Anyway to skip the whole CSRF checking thing based on my own forms?

What would be required to create a user from my own php scritp rather than the registration page from PunBB?

[EDIT]
Nevermind, found what I needed.
