Redirect to join page after logout

whenever i logout it takes me directly to an empty page with only header and footer,so i have to press an item on the header before going to the join page,so my question is how do i redirect to join page directly from homepage.thanks

Checkout the Page Redirect mod which has a lot of flexibility in Redirecting to a desirable page. For example you can set a page to redirect to when members login or another page when the member logout. There are many other scenarios. You can even create a happy birthday page and redirect members to that if they login on their birthday :)
