How do I change what my Categories cards are, or fix a card?

Open your website, then Site Settings and the Content Categories tile. It has six parts.

• Use Categories: Yes shows your categories in the Social Explorer, the cards on your home page and Live Portrait, and adds your explorer page to the menu if the site has none. No hides the cards. Sites made before the switch existed start on No.
• Your categories: every category, each a cluster in your Social Explorer, in the order they show there (drag a row to move it; the first is where the explorer opens). Each has Show in Social Explorer, Rename and Delete, and + Add a category adds one. Years is always the last cluster.
• Featured on home page and Live Portrait: the one category whose cards the Categories block and the Live Portrait section show, and whether the Live Portrait shows them at all.
• Include news articles: also sort your News articles into every category.
• Filters in the sidebar: which filters your Social Explorer shows, with Podspun's pick for each.
• Cards: a tab for each category with its cards: pin a card to the top and drag pinned cards into order, hide a card and Show again, open a card to move or remove an episode or add one, and add a card by hand. A named category (cases, guests, dishes) can also merge two cards and rename a card.

Click Save to keep your changes. They are kept on the site, so a later reading never undoes them.
