NEVER leave the configuation file used to boot HUB within the library
directory.  If you want to leave a copy there for informational
purposes, fine.

  REALIZE that the HELP option in the configuration file must specify a
directory you don't mind being readable.  Normally the internal file
system or IFS of HUB will keep anyone from reading things outside of
the library directory.  HELP is the single exception.

  DO examine your USE log for login failures to see if anyone has been
trying to hack into accounts.  If remote sites offend thee cut them off
(via BANNED_SITES in your config file.)
