Mercurial error: abort no username supplied

Question

Problem on WindowsXP (likely will happen on all Win installs), first time using Mercurial. I found the answer in an inobvious place so I\'m asking/answering the question myself

Answer 1

I had the same problem. What helped me was to put [ui] and username = firstname lastname on separate lines of the ~/.hgrc file. Putting these two things on one line did not work and led to the error.
