+	// 	-	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

+	//		but not on API calls
