elearning - no space & no-dash

Time to change a few things in how we write/spell the term "e learning".

Currently e learning with a space after the 'e' is just not that popular, the most popular term is now just a straight forward elearning, with e-learning on the decline.

How do i know? This comparison of search terms from Google Trends shows what is happening. So I say, lose the dash, and go with "elearning". Remember when "email" was "e-mail"?
