As per
James Kanjo's reply to my question on the forums about how to list all pages edited by a user:
If you precede the filter with a period and search, wikidot will return all pages matching that filter. In James' words:
[…] the Searching Documentation […] describes the syntax to search by users:
* To restrict the search to a specific author, add user:author-name, using '-' or '_' instead of spaces in the user name.
But that only restricts a search result. So to specify all pages done by a user, you must precede the search term with a period:. user:james-kanjo
That searches all pages by James Kanjo.
Hope that helps others trying to do the same thing - and that I haven't stepped on any toes in adding this note in the comments field.
