New reports do not show up in the database

1. Make sure you have set up the mail aliases for your database(s). (See Add a database and Adding another database (Keeping Track).)
2. Try to send a PR using send-pr. If you get error replies, investigate the causes. See E-Mail.
3. Does a new file show up in the gnats-queue directory of your database, with the report as its contents? If it does, make sure you have created the cron job for this database.
4. If the report does not show up in the gnats-queue of the desired database, does it show up in the gnats-queue directory of another database? In this case, make sure your mail aliases are set up correctly; especially, make sure that you have specified the correct --directory option (--database for gnats 4.x) for each queue-pr.
