Friendly Wrong "Username not found" message

[mk0b]

Hi! I suggest adding a friendly user name not found error message. I accidentally put my own username in wrong and I got this screen:

Thank you! I've added a message for using a non-valid username, but not yet for a non-existing username. So, if you submit a badly formed username, e.g. one with only special characters, or one that's only 2 characters, etc., you get an error. But something is going wrong with the error catching that's supposed to occur when the Treehouse server sends back a "Not found" error. I have a couple of ideas, but I haven't had a chance to follow up yet.
