[SOLVED] how to get rid of the "Submited by" text ?

I have created a new content type, which was supposed to be like the default Page type, containing the Availability calendar module (mini calendars displayed for events). My problem is that the page that i create with this content type display the "Submitted By" text with the user and date who created that page and i would like to get rid of that.

does anybody know how to do that ?

thanks
