Chris - thanks for replying. I am pretty certain that koha-admin will allow me
to recreate, but how do I "drop" the existing database? Example: I have deleted
all "branches" but cannot delete the "Centreville"; I have renamed it, but
cannot modify the branch code. All our tests on Marc imports, users, staff, keep
showing up; etc, etc.

I realize that a "delete my whole structure" might be a dangerous "in
production" command for Koha - but that is what I need now - to start with a
clean slate. Do I have to do a complete re-install without the test/sample file?

Many thanks and regards
