Timer for polls
Students asked about a timer to know how much time they have left to answer a question. That feature would be really nice.
Although we haven't implemented a visual timer, you can now set an Auto Start/Stop time on your polls. More info here: http://blog.polleverywhere.com/scheduling-polls/
We've found that even with a timer, the instructor or presenter is really the best judge of when a poll is "done." That being said there are a variety of online timers out there: http://www.google.com/search?q=timer
