It seems to self adjust in width. If you shrink the width of your browser window in will get smaller. So if you were browsing full screen it would look even stranger. It's probably set to self adjust, this way people who browse with different widths of their web browser get varying views.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
