When you sign in, look at the far right of the page. You should see a Unread Posts -. See if you have a Unread Posts + sign. If so, click on the + sign. It should open the hidden Grill Talk menus. I found out a while ago that if you inadvertently click on the - sign, it will hide the category on your signed in page. Your preferences are saved on your sign in page. That may be why you see the different categories prior to signing in.
