eLearning, E-learning, E-Learning or e-Learning?

Hi all

eLearning isn't a proper word and so not recognised by all screen reading software. For those with accessibility issues or developers using an automated tool for quick and easy voice overs the elearning version sounds wrong. E-learning is pronounced properly and isn't inventing a word. Interestingly, email is in the dictionary as both e-mail and email but clearly a far more popular word. So until elearning appears in all the dictionaries, best to stick to the hyphenated version for the sake of others.
