Popular Topics, also called Top Pages on some templates, displays items that are most highly rated by other community members. These items could be blog posts, discussion posts, Groups, Files, or other items throughout the community which supports Ratings.Community members can either view the top items across the entire community or use the filter to focus on a specific content type. For example, you might filter to show only the most highly rated files posted to a community member's portfolio.
Tabs on the lists let members restrict that view by time parameters, for example displaying posts that have received highest ratings in the past week, or month, or over the life of the community.
