A general WP question about contact data

This is not a WPMU question, but a Wordpress question.

I installed a cool lead nurturing product called Leadin on a site I'm doing which creates its own user table in the back end.

I'm looking for a plugin (or something) where I can hook out the same information onto a private page in the front end.

The trouble is, I don't know what I'm searching for. Maybe you can suggest a tool, but if not, maybe you can help me with a search term.

Thank you!
