Sorry. I was striving 2B o so modern. The occasion of my grammatical swamp-diving: “E-mail” has become “email.” So say the lingual lords at the APStylebook. They announced it today in a Twitter post, of all things:

Language evolves.Today we change AP style from e-mail to email, no hyphen. Our editors will announce it at #ACES2011 today.

Perhaps I should have said “swamp diving.”
