There is now a simple way to include a tasteful little search form anywhere on your site. The search form was borrowed from the one embedded into the top of the Newton family of skins. It has no button (by default) and shows a watermarked search icon in the text box as a visual cue. Drop one of these into your site's Menu page to make search one click away from any page of your site.
