You can click on each employee's name (it's a link) to view their Username, Email Address and Activity. The employee Usernames no longer display all together on the employee screen, like they did in the past. However, we are looking at changing this in the near future. There is no report that displays the Usernames, but you can run the Employee Census Report with the First and Last Names and copy/paste each employee's Username from their account into the report, if you need to send something to your client.
