What is the correct capitalization of words beginning with "e-" (like e-mail or e-learning or e-assessment) when used in a title? Is it "E-Learning" or "E-learning" or even "e-Learning"?
To clarify: This question is not about hyphenation of such words (there are lots of other questions about that topic), but only about capitalization, e. g., in titles or at the beginning of a sentence. For the argument's sake, let's assume the words are to be hyphenated. ("Email" is a trivial answer.)
