You're most welcome, Klemm!
Justin, you customize mboard to fit the look of your site by using the same header, footer, and CSS style sheet that you're already using for the rest of your web layout.
I use php header and footer includes for my main pages and just copied and pasted that information into the header.txt and footer.txt for the mboard. I did the same thing with the CSS file, though I remember having to work with some of the more specific elements in the mboard style sheet. Images used elsewhere on your site will need the full URL paths included in the mboard files in order for them to show up.
And ALWAYS save the original mboard files as a different file name (like mboard_original.php, header_orginal.txt, etc) so that if you screw things up, you can always reload the orginal files, change the names back to their old versions, and things will work again.
I changed the name of the CSS style sheet on my board, but if you want to make life easy for yourself you can always save your site's CSS file, updated to fit mboard's need, as style.css (after saving the original with a different name -- again, just in case things gets messed up.)
