Here you'll find a test about more common inaccessibility elements; since it is a test about as 'your' browser sees these elements, we had to put html code in a WRONG form. So, this is the only page, inside our site, which isn't 'Bobby Approved'.
Here I can't find anything strange, indeed.
If your browser can't catch any difference among them, we ask you to contact us clarr@iol.it, we'll send you a version of the pages you're interested in at once, and there will be the inaccessibility elements poited out by ASCII characters and, as soon as possibile (we wish in your aid), we'll put on line a just made version of our site.
