No mistake, it's intended like this. You are not the first one who shows me this "typo".

It's a tradition that I kept from early versions, when I made this hack for vBulletin 2.x (year 2002 I think).
It also reminds me when I used to sleep only 4-5hrs/night while sharing most of my free time with the hackers to come up with all kind of useful edits in the raw vB code...
There were no plugins, way back. To tell you the truth, I like a lot better to edit directly the files. Many people learned PHP because of this. They were forced to watch the code closely...
