Internet, Web, and Other Post-Watergate Concerns

Q. I edit documents used in the healthcare informatics domain, where e-health, eHealth, e-community, e-practice, and other ever-growing variations on the “e-” are present. If the “e-” or the “e” plus a word begins a sentence, I am capitalizing that darn “e.” Otherwise, it looks very strange. Am I correct?

A. For hyphenated e-constructions, we agree:

So far, it has proved impossible to send e-mail without some form of electricity.

E-mail is ubiquitous enough that in several years people may simply call it “mail.”

For a proper name, however, we leave things alone: eBay is always eBay, even at the beginning of a sentence.
