Top charts are a fun way to rank things like movies, names, sports teams, brands, beverages, and so on.
On Savvity it is easy to create top charts. Write your post, check the "Create topchart" box and write some items to rank in the text boxes below the post. Click or tap on the number of stars you want to give each item. Publish.
All users can add more alternatives to the lists. That way it becomes a collaborative effort that can engage many.
