dx_auth user account integration with blog and forum

[eluser]gscharlemann[/eluser]
Hi-

How difficult is it to integrate the user accounts setup with dx_auth into a blog like wordpress or forum like phpBB (doesn't need to be that specific blog/forum)? If I setup a site that creates a number of user accounts and then want to add a forum or blog later, I don't want the users to have to sign up again.

Any thoughts? Thanks
