I am still in learning-process but in my opinion your site is excellent!
Just test your site for example at ' http://www.sidar.org '. This
validator found some problems.
What I miss is a 'skip to main content' and accesskeys.
With ff the text from the main-content overlapps the footer by using the
zoom-function
in some sites, e. g. http://dev5.headclerk.net/about.htm.
