I only saw this once, and I don't really want to keep reloading until I see it again. It looks like a typo in one of the quick tips which cause a link to be displayed literally by php. It makes the quick tip box thrice as wide as it should be and the right sidebar gets pushed halfway to the middle of the screen.

Of course a browser can't zoom images... This quick tip was submitted by souleman and reads "Read the AO FAQ and search the site before making a post.". It shows up fine in the quick tips list, but I got that weird error on the front page"
