If, instead of installing your repository on a server right away, you
had simply typed:

    fossil ui <repository-name>

Then a webbrowser would have popped up automatically and with full
setup privileges.  The default configuration is that any connections
coming from have setup privilege.  You can change that
on the Setup/Access screen.  But the default is useful in that it lets
you set up lots of user accounts without first having to create a
"setup" user using the command-line.

Nevertheless, we will try to figure out a reasonable place to put an
explanation of your problem and its solution in the documenation.
