Answers Unknown
Is it possible to do the following, and if so how:
 * Transclude views of a discussion thread or topic list, e.g.:
 * table of all discussions on a given page (possibly with a maximum length)
 * list of all comments by a given user
 * table of all discussions or comments tagged with a given category
 * more complex queries (all comments by a given user tagged with a given category)
 * Disable threading within certain namespaces
 * $wgLqtNamespaces is supposed to do this, but it doesn't seem to work; an example would be helpful
