I want to know the answer to the following question:
What groups are called Vlachs?
All the background I'm provided with is that "This goes for the Arvanites, an Albanian-speaking group mostly located in the rural areas around the capital Athens, and for the Aromanians and Moglenites, also known as Vlachs, whose language is closely related to Romanian and who used to live scattered across several areas of mountainous central Greece.". Is that enough to answer the question?
Answer: yes
