Having a hard time distinguishing between the RecentChanges list and the Revisions property - not really sure how they relate to each other. It seems I can do pretty similar queries using either, but I suspect I'm missing something.

Still can't get the "titles=" box to have the expected effect (i.e. I expect that results returned are limited to those pages whose title equals the value provided, whereas I'm sometimes getting that, sometimes getting results from any page regardless of title and sometimes getting no results.

I haven't yet figured out how to specify anything other than hard-coded values for page titles, user names etc. For example, if I want to search for all pages whose title includes (or starts with) "The Devonshire Manuscript" rather than pages whose title = "The Devonshire Manuscript"; if I want to include wildcards in the value for the user name, though I can provide a |-delimited list of all user names I'm interested in.
