Using Github internally for work is really nice, but especially when working on multiple projects, some on public and some on internal Github it can also be quite hard to always remember to use the correct username and email for the commits. Because I tend to forget such things I decided to create a little elisp function to make sure the correct user is set when I start magit. Right now I only have to switch between 2 users so it is managable, but I think this is easily extended to more if the need arises (god I hope not).
