For some reason sourcetree keeps guessing my username. I need the whole email address to login but it only uses the part before the @. It is set correclty under options/general, so I have no idea where sourcetree gets my username from. I had the same problem on my Mac a couple of days ago and I was able to change the username, but I can't find it anywhere in SOurcetree for Windows... Where can I change my username?
