On the first page, is there supposed to be a background for the content at the bottom. Where it says, "Click here to chat with us?" I really like the simplicity of your design. I think it's better to keep this type of site simple so that the main purpose would be to focus on finding that special someone. Otherwise if there were tons of features it would be more like a MySpace or Facebook and the purpose would never be accomplished.

I'm not a single but here are a few comments:

stop the loop in the header after one time through. I only need to see it once. It's also kind of slow.

the design looks fine, but there's a busy feel.

there are several different fonts in use. it looks a little busy, and somewhat related, the logo doesn't quite make it. It seems a little old-fashioned in style, and I would think you'd want a logo with some zing to it.

I clicked on the "serve" link, as I wasn't sure how that related to Christian dating. The header on those pages just seems a little crowded, image-wise: logo, rose, photos. The text there is a lot to read; it isn't until I got to the bottom that I found out what your vision is for the service angle. Not everyone will read that far. Ditto on the become and meet pages. There's a lot of philosophical text. It would probably have more punch if it were, well, punchy and more concise.

The left sidebar buttons need a more updated look. All the links there add to a busy look and feel. They're very spaced out, vertically, and on the become page, too many to scan over and get a feel for which one I should read.

The quick preview page has only one link in the header. Have to use my back button to return to the site. What sort of screening do you use before showing people the previews? How much info is revealed in these previews? Some might not want to be involved in a business that does this without more reassurance.

An FAQ about the system they use to match people would probably be helpful. What about some testimonials? I don't mean about faith, but about how this has worked for them?

If I were single and looking for a Christian dating service, I probably wouldn't pick this one. I'd rather use one that does a great job (and demonstrates that they do so by what's on the site) of matching people, rather than the three-fold focus of this one: service, faith growth, relationships. It seems as if the organization people have bitten off a lot. Sorry for the downer, if it sounds that way. The above is just my response to the prospects of using the site.
