Special Note for Windows Users
Explorer for Windows makes a mess of my web pages. However, both Firefox and Safari (recommended) work just fine. All Macintosh browsers are ok, too.
Go figure.
Anyway, if you are using Explorer and the site is scrambled, you have two choices:
First, try selecting a different page encoding. Go to View>Encoding>Western European. It also helps, especially in Explorer 7, to make sure that Auto-Select is "on" in Encoding.
Second, use a different browser. As mentioned, both Firefox and Safari work fine in Windows.
If you want to avoid this notice in the future, just bookmark the next page.
