Home Page Sign In (Your Signed in.....But your not)

[forumsoup.com]

When you sign in my page at http://forumsoup.com Your able to sign in but when it returns to the homepage, it doesnt show youve signed in. The username and password fields are blank but your still actually "signed in". How can I make it to where you can tell that your signed in? Is this a cookie error or something?
