You should be able to put it in a page anywhere on your site.
Maybe a folder and filename like
"/maintenance/scheduled_items.cfm".
I believe you can only add it through the CF Admin to make it
run, there isn't a command under action for 'new' for cfschedule.
It's a good idea to pass/check for a URL variable to run your
schedule within the page. I've had spiders go through a site and
run the scheduled item without me or cfschedule asking it to run.
Hope that helps.
