In addition to managing Pages and Navigation, the Website section of the Manage Team console is where you set up smart content such as Sponsorships.
Go to Manage Team > Website > Sponsorships to manage your team Sponsors and Sponsorship Categories which are displayed in the Sponsorships content snippet.
Add Sponsorships and new Sponsors at the same time by clicking the Add Sponsorship button.
Choose the Category and the Sponsor (or add a new one) for each Sponsorship. Add the sponsor's information (contact info, URL, etc.), add the logo (image formats only -- jpg, png, and gif), and click Save.
Click Manage categories or Manage sponsors to add, delete or edit your own categories and sponsors.
