Well, I might be all wet, but I think something has changed with the message board code, either a style sheet or some resize logic or something. It's different than it was.
Plus, if you look a the Wood Carving Illustrated home page and the screen when you are reading a thread, they look alright. It's the main message board screen and the 'New

s' screen that are sized strangely. I also notice the User CP screen is wierd, but if you go into Edit Profile, that screen looks ok.
Something's up....maybe one of the web techie's for WCI could look things over.
