title: meta box for header
body: <p>I actually searched on the web about meta boxes but didnt find the thing I want since they were page and post specific .  So I am actually searching for a thing(meta box or whatever) which will  provide me a simple text field in the admin panel and when I enter the link of the youtube video and hit submit the video would appear in the HEADER of my blog . So which tool will let me to do the thing I described ? </p>
