another choice to the poll.
* `total` - Show total number of votes at bottom of poll. Default is "yes".
* `percent` - Whether to display percents. Default is "yes".
+* `postvote` - By default after voting the updated page containing the poll
+ is displayed. This parameter allows advancing onward to another page.
+ This is useful for multi-page polls.
+* `posttrail` - Similar to postvote, but allows advancing to the next page
+ on a trail after a vote. The value of the parameter is the name of the
+ page that defines the trail to follow. The trail plugin must be
+ enabled for this to work.
