Yeah, just plug it in. However one really nice way to use UDFs is to create a library of them, which is just a file with a <cfscript> at the top and a </cfscript> at the bottom and a whole bunch of functions in between. Then you can cfinclude that library whenever you need it (you could add <cfinclude template="myfavoriteudfs.cfm"> to your application.cfm file -- doesn't seem to affect performance).
