The search bar and tags are the main way to browse content on Ingenuity. You can simply filter the home feed for the tag you are interested in and see all related content for it. Using a tag is also the simple way for you to create a landing page for a topic you want to promote.
This can be an event, a project or a trending topic. Moderators can create a header component for this topic by adding an image and a description for your tag in the admin backend. Just ask your moderator to create it for you.
