Having looked again at the Wizard I don’t think this is possible. Please correct me if I am wrong about this or take this as a feature suggestion.
I am using the Category based home page (Categories + latest posts) and that’s mostly great. But I would also like to be able to pin a single “Welcome - What kind of community are we building” over the top of the categories.
Is this possible? Is it something I could do with a theme? Or does it need support from Discourse itself?
