Looked through the knowledge search and found a topic that was close to this, but did not have the remedy I am looking for.

Under Users > Username is my Admin profile.  There are no others on the board yet.  When I open my forum, I want the username to say "Admin" and not the name it pulled from my hosting account.  Attached is the no-go message I get, and presumably everyone else gets as well.  I do not want my Admin username to be my hosting name.  Is there a workaround for this?
