When I was trialing AC on an old computer, before I put in any real patient data, I found this problem. There seemed to be no way to change the user name once it was set. You only got a chance to choose it on initial setup of a user. So, when I set up the real practice for my office, I set user names as 3 letter initials, rather than first names. To me, this seems much more professional, and clearly identifies a writer in the chart, rather than just the first name.This tip might help someone who is just getting started, thus I am noting it here.
Hopefully, support has a method to correct it after the fact.
