-	// 	-	the length that the caller wants to truncate the content preview to
-	//	-	a boolean that indicates if the caller is from an API call

-	// use the content field and create the preview from that
-	//NOTE:****  You have to make this a system plugin if you want it to also work
-	//		on API calls.  If you just make it a user plugin it will work on web page output
-	//		but not on API calls
