Here's a workaround that will allow you to share your poll with another presenter.
1. Copy the URLs of the polls you want to share onto a list. (Copy the address while it's in live chart view, not instructional or survey view.)
2. Give them the list of URLs.
3. Have them log into their own Poll Everywhere account.
4. Have them enter the URL for the first poll, and then add this: /copy to the end of the URL.
5. Repeat for all the polls on the list.
They'll appear in their My Polls account, just as you have them now, but without your results.
