db@ I have handled untold cases in which the client is a corporation or LLC, but its domain name is both different from the entity name, as well as the site slug/name. (E.g., Dongle Holdings, Inc. does business as Bob’s DongleLand, with its website at dongles-x3.com.) This is all fine and good, until you try to clarify it in a lawyer letter or court filing.
When the client’s domain name needs to be emphasized, the tendency is to say “dba dongles-x3.com,” except Dongle Holdings is not doing business as dongles-x3.com. It’s doing business at the domain. So “db@” is the quick path to clarity. (Now: Dongle Holdings, Inc., dba Bob’s DongleLand, db@ dongles-x3.com.) Yeah, I made it up. Yeah, I have not seen anyone else use it. But over many years, no judge or clerk or attorney has ever questioned it. Meaning, the point was made. And that is what language is all about – getting the point across.
