It’s not something you need to be concerned about. It was not a phishing attempt and we have not been hacked. You do not need to change your password.
It’s basically a test site that we use to test changes to the SDMB software. We have been testing some things, and since the renewal time for all of the charter members is coming around, our test copy with our modified SDMB decided to send out reminder messages, just like the real SDMB does. We are testing with an old stale copy of the SDMB, so if you have renewed your membership, the test copy isn’t aware of it, which is why it kept sending out notices with incorrect dates on them.
Sorry for the confusion.
