Depending on account it's either Mike Alpha Romeo or Tango Echo Alpha or sometimes Hotel Oscar Lima
I don't love my Commander name (MetaAverroes*) which was chosen in some haste with very little thought when I first installed the game on the erroneous assumption that I could easily change it later.
However, I soon realized that while I would happily have been rid of the name I was indelibly Mike Echo Tango, having been called that by every station I approached. It took me ages to come up with a better name that also started with M E T, and in fact I've never got round to putting in a ticket to ask for it to be changed.
*The first name to pop into my head was the (I thought) obscure Arabic philosopher and astronomer Averroes. Not that obscure, it turned out. So then I thought, what comes after Averroes?
