Other information: If I see a logo that I really like, I will end the contest much sooner than March 15th, 2006. The sooner the better. You must also be willing to make a few edits to the logo, if I see that something needs to be changed.

You have to let the contest run it's full course. This gives contestants a fair chance at entering.

Also this contest seems to be a contest for a website header (including the logo), not a just a single logo.

Please also specify a width, as your comment: "and a width that encompasses the whole screen" is too open for interperetation due to many screen resolutions. You could say you need a liquid header that can stretch from a minimum of 800px wide.
