This paper focusses on the (re)design and conversion process of small-scale English as a Foreign Language (EFL) online courseware into a Massive Open Online (Language) Course -- or LMOOC, as it is commonly termed -- for upper-intermediate learners of English offered on edX, one of the most popular MOOC platforms. It stems from the "InGenio First Certificate in English Online Course and Tester" (Gimeno-Sanz, Martínez-Sáez, & Sevilla-Pavón, 2011), which provides university students with autonomous study and self-evaluation materials for the preparation of B2-level official English language exams. The authors discuss the differences between both platforms and the implications for language learning. They conclude that it is necessary to build language-learning-specific add-ons onto currently available MOOC platforms. [For the complete volume of short papers, see ED590612.]
