Has anyone seen or used an online membership directory script? Surely one exists.

I have not extensively used wordpress before, but we started playing around with it to use as a platform for our church's Junior High Youth Group. The intent of the site is to be for the kids (and hopefully their friends), not a description of the ministry. We crammed every cool new technology into there that we could think of.

-A google calendar and rss driven events list (run through feedburner)
-an AJAX powered commenting system, polling system, and shoutbox

Please take a look at this site for Church Doctor Ministries. They are a non-profit, church consulting ministry. These guys do great work for the great commission and I am happy I was able to help them with a new website. I have posted for critiques on a couple of other forums and wanted to see if you guys had soemthing to add. I appreciate in advance any help you could give me. Their main site is built in XOOPS and features a blog, a PayPal-based e commerce solution, a custom google calendar events display, custom google maps, and numerous other cool features.
