You can set a project so that anyone can create new cases or community users can create cases. This allows customers that are not full users of FogBugz to submit cases. A link will appear on the home page to enter a new case, which provides a simplified case entry form. If the user is logged in as a Community User, the email blank will be filled in for them.
We find that public case submission works best for people who are working with a known set of users, such as an internal group within the same corporation. Public case submission doesn't allow you to require certain fields. If you need certain fields to be required, or if you are working with a large group of external users, you might have better success creating a simple email form and leveraging FogBugz email functionality.
After submitting a case, they are given a ticket number and a link to track the status of their case:
They can bookmark that link and come back at any time to view the status of that case. Their bookmark includes a generated four-letter password so that their case remains private.
FogBugz will also email the customer a confirmation that the case was received:
This email includes a URL with an eight-letter password that shows the status of this case, as well as any other cases entered using the same email address. Because this eight-letter password is only emailed to the email address the customer typed, and not shown on the web, if the customer knows the eight-letter password, they have effectively proven that they control that email address, so FogBugz lets them see all the cases associated with it.
When a customer looks at a case, they only see their own correspondence. They see the original case as they entered it, and any email back and forth about the case, but they don't see internal assignments, edits, and conversations conducted by logged-on users.
