I've just tested this more... and the module seems to ignore Portals completely!

It picks up latest posts from ALL portals!  I've had to disable the Forum feature in a new website because of this... I can imagine some times this could be of use... but at best as an option only!

David - thanks for the error report.  The module has been updated and is working correctly now.  Each ForumDisplay will only display posts from the current portal.

Additionally we added in a few extra fields that may be useful - GroupID, GroupName, ForumID, and ForumName.  You can see these fields working on our home page.
