From te post by javalizard:

I've been wanting to share with all you something new and special. I've needed to use Wordpress Multiuser as blogging software (it's supported and has new releases once in a while and people know how to use it) with PRADO. Auxiliary is the integration of BBPress too. Basically, it's a single login system for prado, blogs, and forums.

This setup lets you manage user information (roles, permissions, abilities) for WordPress through PRADO, handles user authentication and applies WordPress code libraries (actions/filters) and plugins.
