Please download the and apply the latest updates available. There
were some bugs in the user management that I had addressed with some
updates. Without having my bug list handy, I believe that it was
Feature10003 that corrected this. I never attempted to remove the
admin/shellie account. I will have to check my code but I thought
that I made it so that you couldn't remove the admin account so you
wouldn't get locked out of the interface.
The email address should be set whenever you first install it and run
the setup. You should also be able to change the Email address via
User Management. Please let me know if that isn't the case.
If none of this addresses the problem, please let me know and I can
see what I can do to help.
