I am not new to the Dell community, but I am having a problem with posts. Posts display a handle at the top, in this case, nmgdcrpjq. I wish to change this. This is not my user name. I am trouble finding where to change this in my settings.
The username cannot be changed. Here is your user profile page. It shows your username in the top blue, under latest post, and on the bottom right as nmgdcrpjq.
