I agree with Invision on the "happiness" of your site. I, however, think that you should make your body background white. Part of the reason is that, though your site works well in different resolutions, the larger resolution screens (like 1024x768) allow too much black background bracketing your cheery page.
Also, the "Schedule of Services" navigation image has a bright green background color, whereas the rest of your nav images have the aforementioned black background. Here is the code in your source:
<TD COLSPAN=4 BGCOLOR=#33FF00>
<IMG SRC="images/sked.gif" WIDTH=140 HEIGHT=24 BORDER=0 ALT=""></A></TD>
Simply remove the "BGCOLOR=#33FF00" portion to fix it.
While attempting to run your site through the W3C MarkUp Validator, a fatal error occured stating that no document type was specified. This should be at the very top of your page's code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
This should work as the Document Type Definition for your pages. If you want to learn more, do a little research at http://www.w3c.org.
Be sure to install a working forum so that your church and church members can use it to interact.
All in all, though, good job!
