I want it to show on top of every page , i have the conditionals set for guest/member

--------------- Added [DATE]1215408358[/DATE] at [TIME]1215408358[/TIME] ---------------

I have stuck it in there manually on the header templete , i want to call it so it dont show up to SEO bots and slow down page loads ,

It should be in header includes maybe?

Thanks For any help
