Below is some example text to describe the participation process to your participants. This could be included in an invitation email or in a 'heads-up' email sent prior to the invitation. Feel free to copy the text and edit to suit your needs.
We're using a new tool called ThoughtExchange to gather your input. You'll be asked to answer one open-ended question with as many responses as you like and then move on to the next step which is Star. In Star, you'll see your thoughts and the thoughts of others and assign stars to each thought (from 1-5) depending on how strongly you agree or disagree with the idea.
ThoughtExchange keeps confidential who shared each thought and who assigned what ratings. You can rate as many thoughts as you'd like before moving on to Discover where you can see all the thoughts sorted by the average star rating.
You can also navigate by using the bar across the top to go back and share more ideas or star some more thoughts at any time.
Also feel free to share this video that outlines how a ThoughtExchange works:
