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

Okay, so a lot of this discussion seems to be focused around the use (or not) of the hypen between "e" and "learning."

However, given the number of job titles that now BEGIN with ... it. Is there now a generally accepted way to call oneself , for example, which would it now be considered... 

E-learning Developer ?
E-Learning Developer ?
eLearning Developer ?
e-Learning Developer ?

( I recently got busted for calling myself an eLearning Instructional Designer, but then, two jobs later....  Elearning Developer... in my resume, and I/m trying to correct it)

THANKS!
