It doesn’t matter what email address I have if I don’t get a response.
I still have not had any response regarding requests for a password refresh.
I do the support of the database for free. All I expect is an acknowledgement so I know when problems have been resolved. For 99.9% of cases this is the case. In fact I receive unsolicited thanks all time and that’s wonderful, really makes my day when that happens.
But it’s hard to know a problem is fixed if you don’t get any reply.
