Integrate Wowbb Database with dating script

I have a small dating site. I would like to integrate wowbb ([login to view URL]) fully with my dating site so that logging into one also logs you into the other. I would also like to replace my dating site's private messenger with the private messenger that comes with wowbb(It has a wysiwyg editor) and have it so that it Displays a thumbnail of the person's profile picture in the message, and allows you to send and have it so when you click on a name in the BBS, it takes you to that person's dating profile. Security also needs to be set so that a person who is not a paid member cannot post messages in the forums, but may view them.
