I'm editing a template which controls the activity feed for the main page of the wiki. I would like to exclude the User and Message Wall namespaces from the feed. I have looked at the help page for activityfeed, but the syntax there is not overly clear. I have also looked at the help for Namespaces, so I think I understand them. Anyway, my attempt to exclude these namespaces has not worked, so I need some assistance. Thanks in advance.
