Make sure when you log in that you check the little box to stay logged in. If you don't, the forum will time you out. this is helpful if you are using the forum on a public computer. If you log in with the boxes at the top, the box is already checked. If you log in with the box in the center of the screen that states you can't perform this action because you are not logged in, then you must check the box. Hope this helps.
