I notice that some users have Medals & Awards displayed under their rank insignia, is it possible to show campaign ribbons in the same way?? I've checked in my profile etc and can't see any way of doing so.

Dave, the only ribbons and medals you'll see on a member's posts in the forums are the "Golden Rivet" medal for user of the month and a "Moderator" ribbon. And the "A" Guard pin.
All other medals and ribbons are viewed under his/her profile page.
Who knows, maybe another day Jim will allow one or two of the campaign ribbons/medals to be shown on your posts.

No problem, thanks for letting me know.
