I am one of the CHEESE administrators and I have been blacklisted by some schmuck from using the CHEESE admin functions cgi script. Now what?
At this point, you have to clear your entry from the blacklist database by hand. Use chdblist to list the contents of the database; look for the urls with your user name in them. You can use chdbdeluser to clear out all entries with your name in them. These programs are both run from the command line; see the CHEESE documentation for details.
