For several years now (as long as I've paid attention) almost every ad or commercial for a bank or credit union says they are Member FDIC or Member NCUA. Where is the of? Why are these not Member of FDIC or Member of NCUA?
I've never heard somebody use the term member without of or some comparable preposition.
Tom, are you member Costco? Yes Bill, I am member Costco.
I've never seen an instance of this. What gives?
