When doing a user summary including multiple spaces, it would be handy sometimes to group results by space. (ordered either by number of edits/comments or by last update or edit) Something like: {contributors:columns=edited,commented,watching|spaces=Help,FAQ,Other|groupby=space|order=editTime}

SPACE	Edited	Commented	Watching
Help	James	Shannon	James Shannon
FAQ	Shannon
Other	Shannon	James	James
