Thanks, MoR,

I am / was among those interested to hear about the Broad Riband, including civilian Black Tie.

I am a member of an organization that bestows a medallion (on a neck ribbon) on its past presidents, but has no badge of office for the current president. I had thought that a sash in the same color, not unlike the Order of the Arrow, might be a good insignia for the office, but got no particular enthusiasm. We may end up with a chain, like a Lord Mayor's, or some kind of staff, like a bishop's crozier. Or we may stick with the status quo- zip. The president appears only once or twice in full dress during his year of office, so it may be simplest to remain unencumbered. Perhaps a live badger on a leash...
