Noun. Edress in BBS days refered to the specific memory location within a
computer system where electronic messages could be left for a person or organization for later retrieval.
The name
e-mail later won out over edress (
maybe it sounded too much
like clothing?).
Edress is still used today to refer to a name or a sequence of characters that designates an e-mail account.
I first coined this word back in the 1980's BBS (Bulletin Board System) days of computer science (Someone else may have thought of it before me, but I thought of it on my own as well).
