From the menu on the left, click "Edit Options". Scroll down to the section headed "Thread display options" and make sure the boxes for showing signatures, avatars and images have a tick in them. Scroll to the bottom of the page and click "Save Changes". That should fix it.
EDIT - So whilst I'm spending my time typing out an explanation for you on how to fix your problem (which, incidentally, you could have done yourself if you'd bothered to look in the appropriate place), you edit your post and flame the forum? You clearly have contempt for the site and have very little patience when posting a plea for assistance. Perhaps you should just be banned, would that make things easier? After all, it does "suck" here, apparently.
To get the glow just go to the Store. The link to the store is just above the first post within the thread. However, in order to buy a glow you will have to have a certain amount of points, which are displayed in the profile under your username. There are also different options such as Thief, Bank etc in the store.
