It's not clear to me what this top level wiki wants to be, so I have created a separate wiki for unstructured notes and journalling:
Search works in a particular way in Federated Wiki, specifically it looks in sites that are in the current Neighborhood (_sorry, it's American English_). To add further sites to the Neighborhood, click the blue chevrons to the right of a list of site flags in one of the boxes below
