somethings going on with my cookies. i can usually log in fine and roam the site for a good amount of time, but then out of nowhere if i try to post or look at the mod's forum, it says i'm not logged in and makes me log in again. then i'm usually able to roam for another little while before it does it again. it's not only when i try to post. sometimes when i go into the main forum directory, i can tell it's logged me out because there are no red stars in front of any of the topics. anyone have any idea what's going on? because it's REALLY annoying.
