(Pardon the latency on this post. I had it in the Drafts section for a while.)
When a website requires a password for registration, said site SHOULD NOT EVER mail you back the password in the clear in an e-mail. Let me repeat that... SHOULD... NOT... EVER.
One of my daughters plays soccer, and has for two towns. My whole family enjoy seeing the Boston Breakers play soccer too. Both my daughter's town website (outsourced to Blue Sombrero) and the Boston Breaker's ticketing website (run by PMI ticketing using TicketSocket's technology) made the aforementioned mistake. Both of them, quickly addressed the issue with direct and up-front e-mails. I believe Blue Sombrero addressed the problem a bit quicker, but that's because of a combination of smaller organizations and the Breakers' mistake happening on a weekend.
The Blue Sombrero handling of my daughter's old town website mistake was quick, and without incident. Hats off (no pun intended) to the Blue Sombrero folks, who I hope have implemented the no-mailing-passwords policy throughout their entire customer base.
One bad thing someone in the Breakers organization did was remove my original complaining posts on Facebook. I suspect this was merely the case of panic and not active malice. The General Manager of the Breakers, Andy Crossley, sent me a mail on Saturday to see what was going on. Once he understood the problem, he got the relevant technical folks involved, and they solved things.
While I'm glad to see quick turnaround on these flaws, the one piece of advice I will reiterate is NEVER SEND OUT CLEARTEXT PASSWORDS. Thank you.
