At the moment, Medical Sciences SE has tag fda-food-drug-admin for the U.S. Food and Drug Administration (FDA), without any synonyms. Since food-and-drug-administration is too long, I propose that the aforementioned tag be renamed fda or us-fda.
As an aside, I must say I wish tags had history trails. I really wonder who made so many tags of the form [thing]-[synonym-for-thing]. Somebody really liked hyphens and really long, specific tags.
