After quite a long period and a bit of effort on a number of members of FAmSCo, we have come to the realization that exposing the trac instance to public view is essentially not possible. Each solution we arrived at placed us further away from transparency that the situation now is. The reasons for this are given below.
A significant amount of information that contains personal data is contained in the tickets that currently exist. Those include addresses, bank account numbers, credit card numbers, etc.
Moving forward, additional tickets will be created that of a necessity will require submission of personal data for reimbursement. (FAmSCo considered having Max be emailed directly via an encrypted email, having encrypted data be submitted to the trac instance, and a number of other 'solutions' that proved in FAmSCo's opinion to be unworkable.)
