I need to respond to an e-mail sent to me by a committee (e.g. ABCD Organizing Committee). In the distant past, I would use something like "Respected Sirs" but that seems archaic now. How would I address such a committee now?
The committee's e-mail to me started of as "Dear FirstName LastName, " and then proceeded to extend a formal invitation.
Also, I decided to go for "Dear ABCD Organizing Committee"
