A little about me:

As you can see, my name is Mark McIntosh, but everyone just knows me as Macr

Macr (Mäck Āh)[Colloquial], n. A nick name, generally used for surnames starting with Mc or Mac. Commonly spelt as Macca or Macka.

The last sentence explains why I spell it as Macr, because I wanted something different. This all came about when I used to live in the Northern Territory (N.T.). I tried to get Macca as a number plate, but it had already gone, so I came up with Macr as a derivative and it has stuck ever since. I actually don't like the other two spellings now, but I bite my tongue if people do spell it that way when referring to me.
