How to best Integrate Dolphin with Wordpress?

Is there a best way to integrate my Wordpress site at http://www.celebratecycling.com with my Dolphin community at http://www.celebratecycling.com/friends?

I suppose you could create a bridge between the databases to link accounts, as well as have registration on one web site disabled, so that registration on web site A also creates an account on web site B.

If you do not know how to go about this, I suggest you post a job offer.

What are the stuffs to be integrated between them?
