Contact your hosting provider is my suggestion. Even if you fix up the home page link, if someone manually types in your webbie url then it would probably not have the "www" therefore they login in then to find out they visit another page and "appear" logged out.
Andy did a tutorial on how to make your site stick as "www".whatever.com - I can't remember the thread, but it is real simple. At least that is what I remember.
Ask Andy
Plus, let me know I bookmarked and then FF crashed and I lost all my cool bookmarks.
